91 Silverado-rearend Info

Have a 91 silverado shortbed half ton reg cab. Can anyone tell me what year rearends fit this truck. I will be looking through flea markets this coming spring for a rear end and am looking for info as to what will bolt into this truck as far as years, and models, also, are the ring and pinion gears the same from say the late sixties up 10 bolts or are these trucks a different animal. thanx. wnk.

prob a 3.73 but check the codes in your glove box ig you see GT4 you got a 3.73 rear end!
