15x8 w/ 4.5” BS on front/good handling size?
I tried some 15 x 7.5 slot mags on the front of the beater a few weeks ago…4.75 back space… they hit the upper A arms… maybe a steel wheel would work clear….

On the factory front end, 3.75 bs is about all you can use, before the wheels get into the upper bjs with 15s....... and/or the rubber gets into either the strutrods, the frame-rails or the fenders.
BUT IMO,
almost worse is that as the center of the wheel moves outboard of the design centerline, this creates a scrub radius that tends to manifest as wandering in a straightline, which for a streeter is the death-knell of long-distance cruising. Even a half-inch is annoying by 40mph or so. Which is why I went back to a 7.5" wheel, and a factory-height tire.
but, the backspace of 3.75 on a 7.5 wheel, (which is 8.5 from outside to outside) pushes the wheel centerline about a half inch to the outboard of the design centerline, and so, my car does wander some, on the hiway. To combat that, I pump up to pressure to 32, from the usual 28psi, in the 235/60-14s.
BTW
I love those lightweight slotmags, and have accumulated several sets of various offsets and widths. and,
They are easy to repair after I curb them ...........
and I seem to have curbed a few.
Those slotmags are about half the weight of a similar-sized steel wheel; and, in town, that makes quite a difference when bouncing thru potholes and hitting speed-bumps.
I get quite a kick when launching over speed bumps at speed, while watching some joker crab-walk his lowered tuner-car over same bump. I give him a lil burp on the throttle as I leapfrog the bump, for a dual 3" canons wake-up call, lol.
But I digress.
Nice-looking car. I had one like that in 1970, except PantherPink/or whatever Dodge called it..... Worst handling car I ever owned ........... but it sure was fun learning to drive it.
