Flywheel question

I need some help. I am fixing to swap motors in a 1968 GMC with a four speed (SM-420). I am installing a one-piece rear main seal 350. So heres the question. What flywheel do I use for the one piece rear main seal motor, but with the mechanical clutch linkage. All factory one-piece rear main seal straight drives were hydraulic clutch.

Thanks!

I've got the same question but in reverse. I'm swapping a 91 5speed trans with an original 350 in.

Re: Flywheel question

I would think you would just install a flywheel for the newer post 86 small block. I don't think the clutch linkage, hydraulic or mechanical would affect it.
