I bought a 9 inch rear yesterday for my 1965 mustang. The guy I bought it from pulled it from under a 68 mustang because he wants to restore the car completely original and is putting an 8 in rear in it. He told me that the car was owned by an older guy for a long time before he sold to a kid who used it for about 3 years as a daily driver to school and then parked it in a barn for 15 years before he bought it. Somewhere along the way this 9 inch rear got put in but he has no idea what it is out of and there is no tag on it. I don't think it is from an old mustang because it has factory disc brakes. I know everything is ford because every piece is stamped with ford. It measures 52 inches from backing plate to backing plate, has a 5x4.5 bolt pattern, 10 5/8 rotor, and the bolt pattern for the piece that holds the axle in is 3.5x2.5. I have been doing some research and think it might be out of a 1977-79 Ford Granada but am not sure. Any ideas as to what this might be out of would be greatly appreciated. I need to know so I can buy new calipers and brakes pads.

DAMNIT...I'm Yong.

 

[Stangmansteve]

Id say probably an F100 pickup.

 

[65BlueHorse]

were the f-100s that narrow?

 

[cindys_sn95]

no they were not! your probably right, granada. very rare.

 

[Blackshadow]

My guess would be a Lincoln Versailles but maybe a Granda. Either way it a great find and will be a great fit. :bigthumbsup

 

[Keving]

68 Cougar. That's where I got the one that is in my Mustang. The width and the spring mounts fit exact. Don't know about the brakes though. They could have been swapped too.

 

[Blackshadow]

The Lincoln Versailles had standard rear disc, and it a prefect fit for a 65-66 mustang only trouble most had a high speed gear ratio for fuel mileage after all they were built from 77 to 80. But just change out your gears to a 3.50 or 3.89. with a t-5 and it a great combo :bigthumbsup

 

[65BlueHorse]

Thanks for all the help. It could be from a cougar that had brakes swaped from another ford but really i need to know what the brakes are. Versailles or Granada is what i was thinking but i thought the Versailles were a little wider. I am going to take it to a parts store tomorrow to see if they can match it up but i wanted to have an idea of what it was to tell them. The guy that i bought it off of told me that he thought it was limisted slip and 3.00 gears but i don't really believe that. Is there any way to check if it is limited slip without takeing out the center section? If the gears are high its not a big deal beacuse i have a center with 3.50 gears i can put in. Don't want to go any lower than that because i only have a 4 spd in it for now (and probably for quite a while).

I just did some checking and the versailles and granada brakes are the same part number so it could be either one. The problem is that the rear calipers cost $85 each (Advance Auto Parts). If this is what i have does anyone know where i might find calipers cheaper?

No buck tag or casting numbers ?

52 1/4 " flange to flange was a Mustang/Cougar/Fairlane Rear end

Sorry to say but there is a number of 52 1/4 rear end from ford not just mustang/cougar /fairlane and most will fit the 65 -66 mustang




1957-1959 FORD BIG-CAR 9-INCH REAR END WIDTHS & PHYSICAL DESCRIPTIONS:


The housing widths are determined by measuring from the inside of one housing end flange, to the inside of the opposite housing end flange. (this would be the flanges at the extreme ends, where the brake drum backing plates attach to the housing).

The 1957-1959 full-sized Ford passenger car 9-inch rear ends had a housing width of 52 ¼" across, flange-to-flange (same as 1965-1966 Mustang 8-inch rear end). These rear ends also share the same leaf-spring perch locations as the 1965-1978 Mustangs with a 43-inch distance center-to-center. (direct swap for '65-'70 Mustang [will give '67-'70 Mustangs slightly more wheel well clearance]. These "narrow" 52 ¼ housings will also fit the '71-'73 Mustangs but wider wheels & tires will be mandatory unless spacers are used with the stock wheels to space them back out.

The '57-'59 Ford big-car rear ends came in two housing configuration styles: (1) Large axle bearing housing. (2) Medium axle bearing housing (same bearing size as early Mustang 8-inch rear end).

(1) The Large bearing housings can only be found in the '57-'59 Ford station wagons and in the '57-'59 Ford Rancheros and also in the *1960 model T-Birds.

(2) The Medium axle bearing housing will be found in all the other '57-'59 Ford passenger cars.

Other Donar Fords

REAR END HOUSING WIDTHS OF VARIOUS FORD VEHICLES:

Measured from the inside of one axle tube end flange, to the inside of the opposite axle tube end flange --(where the brake backing plates bolt to the ends of the housing, and NOT taken from the wheel-flange-to-wheel-flange distance, --where the back of the wheel would mate up to the face of the drum/disk).

1. 1965-1966 Mustang 8 & 9-inch housing width: 52¼".

2. 1967-1970 Mustang 8 & 9-inch housing width: 54¼".

3. 1971-1973 Mustang 8 & 9-inch housing width: 56".

4. 1957-1959 Ford big-cars 9-inch housing width: 52¼".

5. 1960 model T-Bird 9-inch housing width: 52¾".

6. 1975-1980 Granada/Monarch 8 & 9-inch housing width: 52¼"

7. 1977-1980 Lincoln Versailles 9-inch housing width: 52¼"

8. *1957-1972 Ford pickup 9-inch housing width: 56"

9. 1973-1979 Ford pickup 9-inch housing width: 59¾"

10. 1980-1985 Ford pickup 9-inch housing width:??

11. 1966-1977 Ford Bronco housing width: 52¼"

Are you sure you can't rebuild them... just get a kit if the bore is good and not pitted

 

[Keving]

To check if it is limited slip. Turn one axle forward. If the other one turns forward, it is limited slip. If the other one turns backward, it is open.

I don't know if i can or not. I have never done it so i don't know whats involved.

thats what i thought. If i spin one wheel forward the other spins back so its an open rearend.

It's a nine inch from the Granada family ( Versailles, Monarch). I have one sitting in my garage for my '63 Falcon. The calipers can be rebuilt but are said to drive you crazy trying. One thing to note is the t-bolts are no longer available so don't break any. Otherwise rotors ( these are directional so don't mix 'em up), calipers etc. are available. Also the e-brake needs to be set up for proper adjustment of the brake pads as they wear Otherwise you eventually lose pedal):bigthumbsup.

 

[65BlueHorse]

I tried a parts store and a ford dealer today and neither could tell me what i had (i'm not surprised). We took the one caliper apart today and i think i am going to try to rebuild it before i spend the money on a new one. I didn't know the rotors were directional so i will make sure i know which is which. Are you saying that if i don't hook up the emergency brake cable the calipers wont work correctly? My cable broke so i can't hook the emergency brake up until i get a new cable.

 

[rodbender]

The e-brake has a small lever to actuate it. By moving this lever it turns a screw to bring the pad closer to the disc. If you don't use the e-brake the pad will wear and it won't make contact with the disc after a while as the piston action is minimal. Mine came from a 78 Monarch if that helps to give you a reference. Post me the prices if you can I'm curious. It's been a couple years since I looked them up. Oh and let me know how the caliper goes. Best of luck.

Thanks. I will have to see about getting the parking brake fixed. It needs fixed anyway but i wasn't to worried about it before. I paid $250 for the rearend. The best price i got on a remanufactured caliper was $78(federated auto parts) but i can get a caliper kit to rebuild it for $10 (advance auto), the rubber hose that goes from the caliper to the steel line is $45 each (only found it at autozone so far), and brake pads will cost about $20. Thats all i can think of that i will need right now but there could be more. If that is all i need and i rebuild the calipers the whole thing (rear end and all the parts) will run me close to $400. I also have a center with 3.50 gears that i will probably put in it. I will let you know how the caliper rebuild goes but it might be a while until i get it done. I'm kind of low on money right now and i just bought a cheap pickup which needs some work.

 

[Blackshadow]

$250 for the rear end is a great price I was looking for one 4 years ago found one 250 mile away from me but they want $550 I passed on it. Decide you go with a markVII conversion from ultrastang bought my calipers and rotor off a wrecked MarkVII at a pull and save place. Got eveything for $45 but still need to get the support brackets they run $150.

Blue...don't forget about changing the proportion valve, if you could get the one off the mustang you bought the rearend one you might get a good deal if he changing everything back to original.

Just take your time rebuilding the caliper you'll do fine :bigthumbsup

 

[65BlueHorse]

$250 was a great deal thats why i couldn't pass it up even though i didn't know what it was out of. The guy was asking $400 originally but had a couple people look at it and not take it so he told me $300. I offered him $250 and he said he would take it because he needed it out of his garage. I hadn't thought about the proportioning valve so i'm glad you mentioned that.
