Looking for some front wheel tire help on my 64 Barracuda

I'm running 17's on my 65 Cuda, 275 40R17 in the rear and it fits, wheel wells are all stock with the springs moved in and the rear end set back 3/8's of an inch to centre the wheel in the wheel well. I'm running an 8 3/4 with wilwoods disc's on the rear.

The trick seems to be to get the right offset, my rear rims are +24mm with a 5.95 back space. On the front I have 225 45 17's., with wilwwod Disc brakes on the 10" drum spindle. Rear rims are 17 X 9, and front 17 X 8. And yes I have a Percy's fitment tool, and it really helped figure the offset out.

This were purchased from American muscle, yea a Mustang place and found to be very helpful when ordering.
