Not to sound like I'm answering my own question, but I just heard from a guy who took a 240 4spd, dropped an 83 turbo motor into it and swapped out the rear end with a 85 turbo rear. He claims he can get 29mpg @ 95mph on the highway. Anyway, anything seems easier than coming up with a 5spd manual tranny. From my research to date you'd have to start digging through old ladies barns back in the homeland to find one.
I am however still looking for any info I can get on the subject. Calling all cars (motorheads) etc.
