I have misplaced ( can't find ) a container that had bell housing to block bolts, transmission to bell housing, flywheel to crank and pressure plate to flywheel bolts all on original '49 with original 216 engine and 4 speed. Would appreciate any help as to lengths, size, and thread types.
Thanks,

Either method will often make the lost bag show up before I have a chance to install the new ones. You can try to just go to the hardware and buy random hardware. I don't know that the lost parts gremlin is astute enough to know the difference.  BTW the flywheel-to-crank bolts have very shallow heads on them, to prevent interference with the clutch disc. I believe that 350 flywheel bolts will work. Make sure to use blue Loctite on the threads to hold them in place and to prevent oil leaks. Carl
