Track locator

[jerome]

You must run something to laterally locate your rearend. Otherwise, it will move side-to-side relative to the chassis.

A panhard bar is a good choice. Attach it to the rearend (behind it) on the passenger side and to the chassis on the driver's side. Make it as long as possible, level with the rearend. Have a couple of inches of adjustment above and below the centerline of the rearend.

Watt's link is the other choice. Considerably more complicated. Each has its advantages, but I prefer the panhard bar.

Any questions on how to do this just ask. You'll have to fabricate and weld brackets to the chassis and the rearend.
