Looks exactly like the one on my workbench. It's a Saginaw manual box for a '76 and up Jeep CJ. I believe Camaros were the same, but maybe a different ratio.
GM 525, used on lots of different vehicles. It'll have the same bolt mounting pattern as a Vega box. Sent from my SGH-T399 using The H.A.M.B. mobile app
The first year they were used in GM cars was 1964 Sent from my SGH-T399 using The H.A.M.B. mobile app
Looks just like the '64 Chevelle box in my '38 Ford pickup. The splines for the Pitman arm are the same as old Ford, so I'm using the stock '38 Pitman arm on the Saginaw box.
