65 GT Wheels
I just put a set of american racing Torq Thrust on my 66 Cuda.
Front 17X7 with 4" Backset 215/45/17's
Rear 17X9 with 5.8 Backset 245/45/17's
Front has plenty of room and back has all that will fit under the fenders.
The rear rim/tire clearance on the spring is about 1/4"
No Rubbing so far
