I have an 87 Suburban and I just picked up the complete rearend from an 84 Chevy Truck that was at a junkyard. I also got the leaf springs bcuz they had 7 leafs and mines has only 5. (It's a half ton) And when we were taking off the parts, we noticed that the donor truck had a dual driveshaft setup and my Burbie is a straight through axle. I didn't pick up the dual setup bcuz I plan on trying 2 either use mine, or go to another yard and find drive shaft from another Burbie that has the 8 lug rearend on it already. Any suggestions?
