Is 1/2" leaf spring relocation worth the trouble?

Using the A-body 8.75 and 10" wheels, the springs need to be offset as well?

If you want to run tires bigger than 275’s, yes.

Whether you run an A or B body 8 3/4 doesn’t really change what width wheel you can run, it just changes the backspace/offset you need on the wheel.
