5 on 4.5 bolt pattern. stock backspacing is about 5" (correct me if im wrong) almost any yj, tj, zj and other xj wheels will fit but i believe yjs and tjs have less backspacing, im not too sure about teh backspacing on zj (i believe cjs, wjs and kjs have 5 on 5.5??) im not sure on the grand waggys. ford made some cars with the 5 on 4.5 pattern. umm... thats about all i can think of for now.
virtually any Jeep

-pre 06 Wrangler
Rangers, crown vics, escapes/tributes, 5lug mustangs use the same bolt pattern. Same goes for the magnum/ charger/ 300c (the last 3 chryslers have the same tire diameter, so you could buy a complete take-off set and just slap them on). If you see a rim you like from another car than just submit the car into a rim search on tires.com to check if they use a 5x114.3 lug pattern (also known as 5x4.5). You're always best off getting something from a 4x4/RWD (20ish offset), but I've seen people getaway with FWD offset rims on an XJ. You can't put rwd rims on a fwd car, but you can get away with murder on an XJ. I noticed backspacing only becomes critical on lifted applications.
backspacing is critical for the way the vehicle handles. if you push the wheels out more with a lower backspacing the car will tend to be a little harder to turn with the wheels wanting to return to straight. if you go the other way, they will always want to turn and you'll have to keep an eye on the wheel to keep it straight.
also, if you get a flat with the lower backspacing, or deep dish wheels, the car will pull violently to that side during the flat.
i like the f-150 and ranger wheels from like 90-93...the small holes on an aluminum wheel. they're on the box type explorers too. also, the new ranger "edge" wheels and sport-trac wheels with the little divots towards the ends of the "prongs".....any five-star wheel ford has is relatively nice.
