1970 Duster, Trans-Am-inspired "Pro Touring" build

So those wheels fit without relocating the leaf springs inward?

Yes, still have maybe 1/2" clearance to the springs. The tires do rub a tad on the fender lips though even after rolling them (beating with a 1.5lb sledge lmao) as much as I could get the steel to bend. But it's not a lot, only occasionally when extreme cornering or hitting big bumps in the road, much less than with my previous wheel/tire combo and if you can see in my avatar pic which is most recent it sits fairly low. Much lower if you look back at the old setup and also consider these rear tires are 1.3 inches shorter in diameter. I need to check clearance to the inner wheel wells but I think these could use a few mm more offset to be ideal. They're meant to be replacements for 2010-2015ish Mustangs after all hence the low price and why I got them.
