GM Saginaw 4 speed ID help
I got a Saginaw for almost nothing that had great looking gears and synchros. I got it all cleaned up, painted, new gaskets and seals, etc. In the process of trying to find out what car it came out of (to get a new reverse light switch which doesn't appear on all models, I got immersed in trying to decipher what this thing came out of. I know the guy's son whose estate these parts were from had a Vega, which came with Saginaws, but this is a 3.50 first gear, and I keep reading people saying Vegas had the 3.11 first gear.
The weird parts came when I tried to decipher the trans code and partial VIN. The trans code is where the side cover gasket goes on, on a pad right at the bottom rear. It is R1P02, which should be R=Saginaw4speed, 1=year-1971/1981?, P=Sept.manufacture-month, 02=2nd-day-of-month.
Now I go to the partial vin at the other side of the main case. It reads 1A7273720. I CANNOT find this format of vin anywhere, especially not in 1971 or 1981! The A was the biggest stumbling block. That should be the body style. 1 means Chevrolet Division. Unless they put an upside down V in the vin, I cannot see this "A" being anything else. I found a body style for about every other letter of the alphabet but A! A-body GM's are Camaros and Chevelle's, but the F-body Camaros and Firebirds didn't seem to have an F in that position.
As far as I can tell it looks like a 1A7?7?720, the first ? mark appears to be a 2 with a little more curl on the top than the latter 2, and the second one looks more like a 3 than an 8, but it is pretty disfigured for either number. Still the A at the beginning throws me for a total loop with the body style. This appears to be a 1972-1980-ish format, as the 81 or so and later got more complicated vins and longer, I think camaros were a 1GNERxxxxx something or other.
Any help??? Canadian VIN maybe??? All the Vin years that I find that are close have the year wrong as best as I can decipher. In just about all possible formats that fit the first two digits, the 5th should be a letter, not a number. and the body style if it is denoted as 72, the only one starting with a 7 is "77" which would denote 2 door coupe and then more info such as pillar, hatchback, etc depending on year. This is perplexing me.
