I already called PATC. They want $200 to do the crossmember if you send them yours. $400 to make one by themselves and then they refund you $100 when you return your core.

For the yoke and U joint, go with Neapco N3R-3-9161X and Precision #534G. What pewter53 listed will be a bastard joint, I was told by Superado that where he works people come in with that u joint broken all the time.

ecsb 2wd is a really easy swap and is ubiquitous now. There is all kinds of great info on this forum if you search and very helpful members too.

 

yea on the 2wd ecsb just get the yoke like GMCtrk said. the drive shaft will fit perfect.. i just done mine and no problems. i was going to do the 2500 yoke but didn't want to have to deal with the bastart joint problems.
wiring is very easy to swap.

 

2500hd 4wd crossmember
