Rambox Rack
Try Nuthouse industries, I looked at their rack at expo west it looks very well thought out.
If I remember correctly they male two heights and versions with or without removable top rails.

I have a set of Toyo Open Country A/T's 295/75 r16 load range E on my 97 and love them.
I put them on with stock 179,000 mile springs and I did not have any rubbing issues, I have since replaced the springs with
OME stock height springs and 15mm spring packers and the look is great.
