Hey guys, suprised to see more hits on this subject, been busy. There is no tach in my car. When I got it there was no vinyl roof, just the top painted white and there was spots where the trim looks like it was riveted on, but no rivits or screws remain. My neighbors 70 has the same look and his was originally green top and bottom, but looks like it had a vinyl roof. I was able to get the build sheet, but it is a jigsaw puzzle and most of it is missing. I can see where it says special customer order and 4 speed, but cannot find anything about the engine.
