stock rims don't have 3.75 backspacing, so if you are going to order a new one, get all 5. But you CAN find stock CHEROKEE rims with the 3.75 spacing if you check around, auto salvage yards, a cherokee forum, etc. (google search for XJ forums-I can't remember what they are, I think one is NAXJA?) and then you'd have stock rims cheaper than new ones. Ran into this with rims on my YJ...stock rims didn't have the backspace for 10" wide tires, son found me a set of XJ rims to fit.
