10" clutch? What the heck flywheel do you have? Since when will a 10" clutch fit an FE flywheel?
There are only two FE flywheels used from 1965 thru 1976 on 352/360's & 390's.
390: C5AZ-6375-L / Marked: C5AE-6380-K / Uses an 11 1/2" clutch on a 12 7/8" bolt circle.
352/360: C5AZ-6375-K / Marked: C5AE-6380-J / Uses an 11" clutch on a 12 3/8" bolt circle.
Both flywheel's ring gears have 184 teeth.

Gypo's: I kinda figured that, but who in the world would want to use a 10" clutch with an FE engine? In-adequate is not the word for it.

Hays is an ok clutch....IMO not the best... I've had really good performance out of the McCleod clutch and pressure plates. Clutch selection has a lot to do with what you are using the truck for, how much horsepower and torque your putting out, and how much $$$$$ your willing to part with... Ram is also a good street type clutch, ran one in an FE powerd Mustang and was very pleased with it.... Both Ram and McCleod have very knowledgeable and helpful techs on their tech lines.....

Geeze the clutches for these are friggin' pricey! Napa's is $200, Checker wants $320, a Centerforce is $420. LMC carries two kinds, one for $200, and one for $240. I don't know what the brands are other than the Centerforce, but I would hope that ALL of them are made in the USA, otherwise I'd find it pretty much outrageous if they came from overseas or Meheco.

My guess is that the clutch you have now is not a 10'' clutch. Its a 11'' for a 360/352 engine. You need a 11.5'' clutch and flywheel.
You need part # 747 and part number MU10111 Online Auto Parts and Auto Accessories Store at PartsAmerica.com
For under 250.00 you can get a new flywheel and complete clutch set.
