I've recently got a 50 3/4 3600 4spd. It's my first experience with these trucks. If your 53 has the same rear as mine, the original gear ratio was 4:56. Based on my research, the 67-72 3/4 (C20) has the same "guts" as ours. If you can find one that had/has an auto transmission, then the ratio should be 4:10. You can pull the whole gear assembly out and bolt it right into your housing, using your original axles. Then you will be able to travel faster than 45mph without blowing it up :-) I found one for $100 and am going to try it out.

my truck has a 4:11 from the factory it even says in the manual
it has a four speed mabe that makes a differance but a 4:11 won't make much differance the truck will still be slow. you can get a 3.55 from chevy duty for only $400. lol

There is a man down the street that has a disasembled 55 3/4 ton gmc for sale. the body is in pretty good condition. He is wanting 400 for the whole thing.
