Jeep 4.0 in 69 Barracuda

I can’t give you any recommendations based on your setup but if you can use the wheels you currently have, it will save you some coin for something else.

I had that problem as I have 2 sets of wheels- a set of Mirada 15 inch 10 spokes and a set of 14 inch Magnum 500’s. I knew the 15 in rims would fit my Dart with 4 wheel disc brakes but decided to see if the Magnums would fit the rear with Mustang based discs. The Magnums cleared the calipers by about a 1/4 inch. That saved me from having to buy another set of 15 in wheels as my 47 definitely requires 15 in wheels - perfect for my Mirada wheels
