Racing slicks n wheels

Like what
I don`t have a valiant, but my guess would be to massage the heck out of the inner fender wells, the outer ones as much as possible w/o denting the outer fender, and offset spring hangars. 8" wheel maximum, w/ a perfect offset, and rolled outtter fender lips, w/ the front fender
reshaped to the inner fender contour(before paint). I have 295 65 15 draq radials on a 68 barracuda done this way. I am assuming the fenderwells are about the same on these two cars .. ????
