Doing a clutch job on my '69 Mach1 with 351w and 4 speed. Present one has been resurfaced already and has heat cracks. Can't afford $300 part at this time. Any good sources?

Where you seeing $300? Summit and Jegs have all the varieties that you are likely to need and I am sure they do not come close to that price.

Check your diameter, your teeth count and your balance factor and check them out!

Didn't go far enough on the Summit site. Didn't understand balance factor but I do now! $65 is more like it. Thanks!!!!

Ordered flywheel from Summit, all the right numbers but when I got it, the pressure plate bolts didn't match the tapped holes. The pressure plate uses 6 bolts. Talked to Summit cust. serv. and they couldn't find a match. I looked at Jegs and the application chart showed the 351w replacement starting at 1970. Don't want to send back another wrong part. Paid $30 in shipping so far.

Sounds like a miss-match of pressure plate bolt pattern. What's the Summit number? Most flywheels are drilled for the three different bolt patterns of the different style pressure plates. The 69 probably came with the Long style with the three fingers and those bolt holes are not equally spaced like the diaphram clutches. Just South of you in Stevens Point, got three different flywheels/PP set-ups and all the flywheels have three sets of six bolt holes. The one from Dallas Mustangs only has the early style bolt pattern.

What diameter clutch do you have? There were 10 1/2 and 11's.

Yes, the only problem seems to be the pressure plate bolt locations. The Summit flywheel had The right bolt circle diameter but the spacing for the bolts on each yoke was about 1/4 inch off. I can provide pressure plate mounting measurements when I get home in about a week and a half. (writing this on the road hence the long time to reply). I will get back to you to see if you might have the right part.

What is the number of the Summit flywheel and which style of pressure plate are you using? Did send you a PM.

Still haven't found a flywheel to match my new '69 mach1 351w pressure plate. The ford number is C5AE6380-E. It has 164 teeth ring gear, 11" clutch,26 oz. balance factor. Summit or Jegs have nothing to match the pressure plate. (3 7/16 o.c. bolts)

Ebay! There's a bunch on there. Right now!
