wheel spacing help !!!!

[davepl]

With the price of decent wheels being what it is, I'd invest in one of the backspace measurement tools. If you have the tire you plan to use you can mount the tire on the tool, slide it inboard and outboard until tire clears (or doesn't, if you're unlucky) and then take a reading from the scale on the tool. It will tell you exactly what the backspacing needs to be. And of course if you have a means of doing so (spring out, etc) you can check the full suspension travel. Up front you can also verify it won't hit at full steering lock to lock.

I'd really rather rent one, but if you're going to do it a couple of times over your life, probably a good investment.
