So what all does it take to do a G 80 swap into a 97 2WD 5.7L 4L60E extended cab. Can I swap axle shafts, and keep my 5 lug rims. I guess I could always pull the axle shafts, weld up the lug bolt holes, and re drill them to the 5 bolt pattern. I do work at a machine shop, after all. I need to do this on a budget. As for bearings, we have 4 presses at work, and press bearings all of the time. I guess I would also need to put new clutches in the G 80? Also if anyone has the RPO codes for the gear ratios That would be good too. My truck does good with 342s now, or 373s would be good too, but I would want to keep it to one of those 2 gear ratios. Any thing I should look for or stay way from. Thanks in advance for any help.
