Hi everyone, I have a 77 7.5l 460 that I'm bolting up to a 86 zf5 47. I found the clutch but I can't seem to find a flywheel that's compatible with a 12.25 in clutch. Would anyone possibly have a parts number that I could start looking for them with?

 

77 would be the early 460, and I don't think a standard flywheel was made for them, a 390 from a 4x4 used a 12 inch clutch, and that will work on the early 460, also L&L has them.
