The rear end is so smooth from all the rubbing and scrubbing with steel wool and dawn soap. I was surprised with all the markings that showed up condisering the only one that could be seen faintly was the "A". Probably doesn't hurt that the car spent a lot of its life in San Diego & 15yrs under a canvas tarp too.

I'm guessing the orange and black markings denote 391 gears? I have a chart I can dig up about that. I never realized the diff and rear were assembled the same day though (9/14/70).

The orig owner swears the trans is the original one it came with and it was never rebuilt, although he say he went through quite a few clutches! The VIN is all messed up on it, although 6bblgt was able to make out the VIN 115059 I knew it was messed up when I bought it and but its not a deal breaker for me, the car is what it is. Its going back in that way, and won't get restamped
