Ive read and read and couldn't find a definite answer. I have a 05 gmc 4wd CCSB and finally found a 80 to do my swap in the next few weeks. Are there any vehicles i can just use there drive shafts out of so i don't have to shorten my rear and extend my front one. Thanks guys

 

I believe an ECSB HD2500 has the same wheelbase are your CCSB(baby bed). Shafts from a 6.0/80E truck should work, but you'll have to replace the rear u-joint in the rear shaft over to a bastard conversion u-joint.

Unless there is a yoke for your 10 bolt that uses the larger u-joints. That's something I'm not sure of.

 

Thanks buddy
