Ive thought of replacing it with a dana 80 from a p30 van. I'm also thinking of just swapping the third member out two a single speed. I'd like to here your opinions. Also i'd like to verify that the single speed with fit right into my 2 speed rear housing and match my axles. I have found a single speed diff but it is going to cost me 600 including shipping. I'd hat to get it and find out that it doesnt fit or that I also have to swap axles
or anything else. The numbers on my rearend now are:
3711468
GL109
Can you confirm that these numbers are a 15000lb axle?
From my searching I have found that the 2 speed axle is called a gm t-150
and the single speed is called an h-150. This is for the 15000lb axle. | | |
