I got my new wheels and tires installed finally. I installed P195/60r14 tires both front and rear due to the size limitations for the rear tires. I only have about 1/2 inch between the fender well and the edge of the tire.
I found a set of 4 of these on CL the other day for $300.00. They are 7x14 American Racing AR23 wheels with a -6 offset. The tires are shot but for the price I couldn't go wrong. The AR23's are discontinued in the 4 lug version and I haven't ever seen them on a Ranchero or early Falcon so they should be unique.
