With the right backspace wheel the tire should fit...

Without that information it's a crap shoot...

Assuming the rear is of stock width...

I have a 28" x 8" slick on my 69 with no modifications to the 1/4's or wheel wells...

The wheel is a 50/50 offset with 3 1/2" back but is only 6" wide...

I also have my 8 3/4" rear shortened 1" on each side because the wheels I wanted to use were never made with a lot of backspace...

I do have a 3/8" plate of steel in front of the leaf spring hanger to slide the rear back so that they were not too close at the front at the bottom...
