I was noticing that the rearend/axle is mounted under my car about 1/2" off center. The passanger side wheel sticks out just a little further. The rearend was removed from the car at one time. I would like to slide the axle over and center it. I also want to make sure it stays lined up front to back. I noticed the rubber pads between the leaf springs and axle are looking a little rough. Does anybody make something to replace this? What about something to lower the rear end an 1"? Any suggestions or tips on doing this would be appreciated.
