92 soft top, custom bumpers, self made 3" body lift.
96 4 door hardtop 2wd (for parts)
I built my luggage/junk rack with 3/4 and 1/2" emt conduit and attached it to the outside of the rear fenders.
The front attaches to my self made light bar (also 3/4" emt).
It works great, but has a little shake on the highway.
I have read several posts about attaching to the pinch weld of the roof and sides.
I feel that with 4 attachments on each side to the pinch weld, the rack would hold more than a person would care to load up there.
It would also be a lot simpler, lighter, and sturdier than the long uprights required for frame mounting
I'll post some pictures when I get on my computer
Good luck
