Slant six flywheel for manual trans

@ 65 Cuda 340 - Hell no ! A 53 Hemi 3 spd would have used one but to my knowledge zero gen 2 hemi cars used them.
No, the early 426 Hemi four speed cars used a direct drive starter. I think through 1969. A friend of mine has a 66 he bought new and it has that funky direct drive starter. Rare, and hard to find parts for.

Edit: To add, my 67 Hemi automatic has the normal Chrysler starter.
