The part number on the mounting plate is 1950037. I have attached a couple of pictures also. I bought this back in '85 for my '68 camaro. At the time it had a saginaw transmission in it but I was going to put a M21 in it. I had just bought the car. It was in grey primer with a freshly rebuit 327. I was going to paint the car Lincoln Silver Blue Metallic when I came back from boot camp. Anyway, that never happened. I went into the Navy 5 months later.During the time as was in boot camp my brother managed to get the car started and unfortunately took the car out on the road an totaled it. I salvaged everything I could, the shifter was one of the things, my brother was one of the others. Anyway, the shifter has been in a box for years, and I am selling it on ebay as we speak. I have an El Camino now that is running an automatic so I have no need for the 4-speed shifter.
Thanks for the help,
