Will a rearend out of a 90 Surburban fit a 87 truck?Was Gov lock any better in 90? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I just bought a complete rearend out of a 90 model Surburan.I pulled the back cover off and it is a 3:73 ratio with a Gov-Lock locking diff.It also matches the code in the glovebox.
I read somewhere the axle's were upgraded to more splines and the Gov-Lock was better than the older ones.I am planning to put it in my 87 C10.Will it bolt right in and will the ujoint yoke be the same?
