[mike2/4]

does an one no before i go mesher if a rear end from a 84 1500 will go wright in my 89 or are they different. Thanks

[pmrolfe]

is the GT4 an open diff?

[pmrolfe]

I tried to swap out an 87 10 bolt but it was a no go, brakes were way too big and the axle itself was 2-4 inches shorter. while the 87 was also a half ton like my 94, it wasnt even close.

Mine is GU6, which is apparently 3.42, now how do I know is it's posi or open without trying to do a burnout?

if you need to find your rpo codes if the list in the glovebox is worn off, take your vin into a dealer, they should be able to print you out the list.

I bought a 93 Chevy ECSB and someone has swapped out the rearend from the 10 bolt to a 14, where is the marking on the rear end to find out what gear ratio is in it. The only reason I know they changed them is because I ran the vin and it was supposed to have a 10 bolt. I am pretty sure it has a locker or posi in the 14 bolt because both tires hook up if it spins.
