Mitch yeah check with SLR, think he has a 1.5" one with solid aluminum machine spacers.

The one 4x4parts.com and others sells is from performance accessories I recall.

About a half day job with some help, to make it look like stock you're going to need to match raise the sliders with some custom brackets and both bumpers, think the 4x4parts one comes with something for the stock bumpers?

If you're doing the body lift to clear tires than you have other options if there < 33/12.50/15's. I have some stock 15x7 wheels if you need them with the backspacing to clear up to 33x10.50 inch tires like I use to run. You can always trim/cut the fenders that I did but you won't need to with that combo or even 32x11.5x15.

Body lifts are ok with me and I may end up with one, but there kind of a last resort thing to me..in other words I'll try everthing else first.

I'll help you out on a mod day if you go that route.
