Bill, what exactly needs to be spaced and why? I have aftermarket wheels with less offset so, the caliper rubbing the wheel shouldn't be an issue. Or is it something I need to space to get the caliper to mount? I'm confused.

I am on a really tight budget and can get new calipers loaded for $40 a pop, but if I can get away with a swap for less $ and more time, that's the route I want to go. I skimmed Sky Mfg.'s site and didn't see what I thought I should be looking for.
