Hey all,
Searched about a bit, but didnt come across much.
Working on a 98 K3500 dually project, and robbing some parts from a donor 04 2500HD along the way. Anyhow I noticed it looks like AAM or whoever beefed up the cases on the GMT800 IFS a fair bit. Aside from the brackets that are bolted to the axle, it looks to be the same mounting otherwise. I also found newer style case halfs that said they fit the gmt400 and gmt800 years. Anyone done the swap, or know of some complications I'm missing? The actuator wiring is a non issue.
Swamped with actual jobby job work to be working on the truck lately, but I'll have to split one of the cases open to swap to 5.38's. Might save me some time from pulling the 2500HD axle, if someone has a definite "no, youre stupid, that doesnt work".
