I'd like to get a adapter for my 85, the m20 isn't in particularly decent shape and I have a m50 lying around. I'm not very good at electrical, I'd actually rather just ship my m50 harness to someone and have them set it up for what I'll need if possible? I believe my car uses the square adapters due to the age? I also would like to source a brake booster, and a zf trannie. I'm in Upstate NY.
