I am putting a 4-53 Detroit two stroke in my 68. I know they run away, but I already figured how to stop that. I am looking for part motor and the backing plates for the adapters. I plan on dropping it in next winter if time is permitting. I would like all advice, tips, or tricks for the conversion.

 

lots of detroit guys over at 4btswaps.com

i'm sure you'll find what you need there.
