Skinny Wheel/Tire Fitment 68 Barracuda

Hello all. I've got a 68 Barracuda, still on torsion bar front suspension, Dr. Diff front Wilwood disc brakes with a 5 x 4.5" bolt pattern, and later A-body spindles and upper control arms.

I've got a pair of Mickey Thompson ET Street fronts in 26 x 6 r15 laying around that I was thinking about using.

I'm curious to see what wheel sizes/specs guys with a similar setup are running.

Thanks.
