This LNF is in an autocross race chassis ( The Jeep ) and we are exploring the idea of
installing a 2 speed Powerglide to the LNF. Thus, the obvious questions are: 1. adapter plate, 2. flex plate along with anything else
needed. Any help will be appreciated.

TIA,
Jim

 

I have 1-2 adapter plates left over that will work for you but no idea what people do for the flexplate to get them connected. Unfortunately, I was not involved in that part of the project.
