I had planned on using the door latches from one of my parts cars. The latch looked identical to mine at first, but the lever attachment for the locking rod (inner) does not even come close to mine. It is very different and will not work. I know the latches on my '79 are original. Is there more than on type used on G-body's? I will be looking for another set of latches since mine are badly worn. Am I stuck with overpriced NOS?
