why would the left rear tire stick out further than the right rear tire it doesnt look like the rearend has shifted. " ROOTIN SOUTHERN STYLE''

 

Might be a dumb question, but are the wheels the same offset and width? If so, and the rear end has definitely not shifted (it still sits in the leaf spring mounts properly) than you might have a shifted bed or possibly something is bent. I would also pull the wheels to make sure you don't have an axle trying to come out. I would be really careful driving it until you figured it out.

 

Im going to have to get under and look and check how do you tell if a axle is coming out Ive never delt with c clips its a 12 bolt. Ive always had 9 inch rears in the ford I owned. like I said first chevy.
