I have a 75 1.8L , after much trial and error, (I keep buying 75 1.8L exhaust and found out they dont fit.)
Finally I found one that fit and it turn out to be a pre 75 2.0.
I found a 2.0 banana muffler with some surface rust...i sand it out and painted black ....
so the question is , did the previous owner back dated the header and exhaust?????
I wanted to order that plate from CA DMV, but they wouldnt let me because of the word SIN
