5 speed Dakota tranny?

I'm swapping a Toyota Supra Tranny into my Dart and I'm right in the middle of the process.
Tunnel, propshaft and X-Member has to be modified.
Don't know the ratios from the Dakota tranny but I assume the are good for trucks. Supra and Dakota tranny share the tranny case (R154, AX15).


But I need for my swap the front bearing retainer (where the throwout bearing slides on). Does somebody have this retainer in his garage for sale????
