Ok, I ordered poly-urethane bushings for my leafs. The package I got said proudly, 4WD 88-95 K5 Blazer, Suburban. But later trying them they turned out to be about 1/3 inch to wide. How can this be? Do I have some weird leafs or anything. Well, with that failed, I thought I'd roll the rear axle under and deal with the bushings later. But when I landed the drive shaft on the (what is it called?) U-Yoke, it not either. I always thought and have been told the 12bolt rear is a complete bolt up when replacing a 10bolt rear. Bit the 10 bolt rear seems to accept a larger drive shaft. What do I have to do now? One option is a cusom made drive shaft, but could I order a u-yoke that does fit? Please help.
