I’m looking to fit an a518 on my 78 slant six. It’s in a 78 D100 and the current 727 is starting to go out. I’d like overdrive and a lockout converter, and to do that I’d like to go the route of the early 60s conversion plate and crank extender. If anyone has one I’d be happy to talk. I’m up in northern minnesota.

On a side note what are the numbers for the longer bolts i’d need for the crank flange, and tranny to engine mounting?

I recently bought a whole /6 with trans out of a 64 pickup for those exact parts I got every but and bolt plus the crank extender that way.
