The channels seem solid, the floors have almost completely removed themselves. Not a terrible amount around the suspension mounts, except for the spring seats on the front axle itself. I’m gonna get some rail stiffners and sheet metal and play with it.Avoid anything that has rust in the actual unibody rails. Check around the leaf spring mounts, control arm mounts, etc. If it has rusty floor boards but the unibody rails look solid, I wouldn't worry about it if it's just going to be a cheap off-road toy. I had one years ago that I cut the rusty floors out and welded in some flat sheetmetal to replace them. It was just a wheeling rig so who cares.
Wouldn't worry about any body rust on a cheap off-road toy that's just going to get beat up anyway.
Look for cracks in the unibody around the steering box, not a rust issue but a somewhat common issue on XJ's.
Drivers side west mount looks solid enough, passenger side needs some work but both bolts came out and the nuts are still in the correct spot. I think I’ll clean the rails up and add some frame stiffners before i do much of anything else. After I give it a tune up and confirm it runs decent.Post some pics of what you're working with.
Not as bad as the one I scrapped but that is bad floor rot.
They are just spot welded and come out pretty damn easy. Rosette welds or bolts with washers to put it back together. When I did floors I just removed them from the equation and added them back after the floor pans were finished. Made it actually easier in the long run than trying to fit pans around them. YMMV.The passenger side seat channel is the part I am most worried about. Everything can be ugly, but that has to be strong as well
