I bought a new aftermarket flywheel because the 410 uses a 428 crankshaft and they are externally balanced unlike all the other FE engines that use an internally balanced crankshaft.
The flywheel I bought has to be a little thinner where it mounts to the crankshaft.
I was asking because the person I bought the bolts from swore they were the correct bolts (the longer bolts) which they were.

The longer ones (1") were too long and bottomed against the block. I had to use the shorter ones.

I'm not too happy about the flywheel I bought and I'm not too happy that I had to use incorrect bolts.
It done and runs great.
Thank you and I appreciate everyone's input.

1976 390 mt flywheel bolts
I think whoever worked on this before put the wrong bolts in the flywheel. What size are they?
