If you get steel wheels like cragar soft 8's or d windows they should go on with out any modification. Aluminum wheels will need you to grind your calipers if they will go on at all. Some people say they have to grind a very small amount off their calipers even with steel wheels but most dont.
Hope this helps

15" steels with 4" or more BS will fit, Aluminums will not.

I love the look of the 15" wheels on a lot of guys WJ's on here cause they make the tires look huge compared to mine. I have even seen tires smaller than mine that look bigger and more aggressive just cause of the 15's. Nice rig Seneca!

I have 15's on mine they look great and tire prices are a lot cheaper. I did not have to mod the caliper, but its going to depend on which type you have some have a different casting so you have to grind the little tab on the end down to make them fit.
