Rear Differentail ratio for a 79 Blazer 4x4 W/ 350
How do you find out what the ratio is for both Differentials?
I need to replace the one on the rear of my blazer 4x4
if you can read the RPO code in the glove box thats a place to start,
also I believe there are some numbers on the rear end housing that may
help, you may have to resort to counting gear teeth.
3:42 is a very common ratio for these type trucks.
