Thanks John, I am continuing the search. Seems like the high performance cars are easier to find parts for and they made a lot more of the standard cars like I have. Question.... I have a 68RS with a 327/275 with a 12 bolt rear end. ALL of the numbers match, but the trans is a Muncie (non-matching) Did they ever use a munice on this car? The transmission I have is a 68 camaro transmission, but not the correct serial # for my car.
