Foxbody 5 lug/disk rear end swap.

Hello fellow mustang enthusiasts, I have searched YouTube and multiple forums and things and cannot find the answer I’m looking for. With that being said.

I have an 89 notch I wanna do the 5 lug disk brake swap. Junkyard budget!! I know what parts I need to take off the front of a v6/v8 sn95.

But the whole rear is what I want, so I read the v6 have a 7.5 inch rear, so that’s a no go. But isn’t there a v6 gt? Or are the GT only v8? Just so I know what to pull. There are so many sn95 at the junkyard where I live. Most are v6, I’m only asking because I haven’t found a definite answer so I thought I’d reach out. Thanks

It seems to me that in years back, guys were using rears from Lincolns. You might look into that possibility.

80's thunderbirds were also a source for FOX 5 lug front parts. Some guys even dumped a couple truckloads of money into swapping in the entire independent rear 9 inch suspension system from the 89 T-bird Super Coupe along with. Then too those cars were SEMA level restomods.

I believe,regardless of whatever model you get the 8.8 from,its still gonna require some form of parts swapping to make it work on a Foxbody.As an example,if you get the rearend out of a 8 cyl sn95 (94-95) model,the axles are 3/4" longer than a Foxbody rearend,so this unit would require axles from another model,if you want to have the same track width as the Foxbody.The solution would be to run driver side axles from a 83-92 2.3/3.0 Ranger/Bronco ll with the sn95 rearend.

If youre doing the 5 lug swap for the sole purpose of gaining rear disks and any other benefits you'll be getting out of the swap are strictly a bonus in your mind,a 4 lug rear disk swap is also a possibility,if you wanted to go even more budget.The 87-88 Turbo Coupe Thunderbirds came with a 8.8 with 4 lug rear disks.Whats even better is,the TC's with a manual transmission were equipped with 3.55 gears and the autos were equipped with 3.73 gears.A TC rear would keep you from having to buy new 5 lug rims too.In the end though,either route you take will be a vast improvement over the drum brakes.Improvements can be made to the front brakes too,if you decide to get the TC rear and retain the 4 lug setup.Click the link below and scroll to post #6.It lists everything youll need to do the TC swap,if this is the route you choose to take.

So I’m essentially doing the swap to have easier maintenance on changing brake pads, as well as having more wheel options to choose from. I know there is 4 lug options but I wanna steer away from that. Thanks again.

BTW, to answer your original question, V6 engines and GT trims are mutually exclusive. There is no V6 GT unless you encounter one that's had some work done. In stock form, GTs were V8 only, and V6s were only available in "base" trim.

But who knows what you'll find in the boneyard. For all we know, a GT owner could have replaced their fenders or bumper with base model parts, or a V6 owner might have chosen to upgrade their car with a 8.8" rear end (or maybe even a V8 swap). Fortunately, engines and axles are easy enough to identify at-a-glance if you know what to look for.

Okay, guys I'm back after months of plotting and putting the mustang on the back burner. But I have purchased A 2001 gt rear end. Now I just want to be sure that now all I need is 94-95 upper rear brake hose, that go to 94-98 hard lines, then same soft lines? I just want to be sure here. Im already swapping to svo axels. Im hoping to connect everything flawless, do you guys have better suggestions?

Are you just planning on using parts from the 2001 rear or are you wanting to try to use the entire housing? That housing is a full 3 inches wider than a Fox Rear, I also vaguely recall the control arm mounts requiring larger diameter bolts too. If you were planning on swapping the entire rear housing a pre 99 would have been easier.

Awww man right when I thought I was getting everything together 🏾🏾🏾 So this housing won’t work. Money burned, so gt from pre 99? Does anyone know where to get the hard lines I need?

So i think I found a resolution I’ll use my stock 8.8 I have in the Fox and swap the axles and hardware for disk brakes. Will I need to swap out hard lines for a different year? I have the 01 calipers.

Cool

Ya know, around Christmas time this was sitting in the Pick-N-Pull yard in Windsor. Not sure if it's still there or not. Somebody already did the conversion on a '90 hatchback. Looks like 94-98 GT/v6 front brakes and 94-04 GT/v6 rear brakes along with the 8.8 rear with 3.27 gear.

You should be able to use the backing plates and brakes from the 2001 along with axles from a 1994-1998.
