I need a good set of 3.73 gears and carrier for a 7.5 inch 10 bolt. I was told that a S-10 4X4 (possibly a 4 cylinder) had 3.73 gears, is this true? Thanks for the help, and Merry Christmas!!!

A good way of finding out other than pulling the cover! Open the glove box and find the manufacturers sticker, look for the "GT" code. If it is followed by a 3 it is a 308,4=3.73 and5=4.10. I hope this helps. I've been getting them that way for two years now.

77 and up all GM models exc. Monza/Vega/Starfire, 82 up Camaro/Firebird, 83 up S-series and Astro. Our car is a 79 Caprice we used gears out of a Monte Carlo (metric) and also S-10 gears.
