67 Barracuda Wheels and Tyres

I can tell you the 1st version is to big and will have issues if it fits at all, unless it is tubbed?
I run 255/60/15 on rear with 7" 4.5in backspace and have a good full well without lateral rubbing, maybe an inch clear either side. Front 215/70/15 on a 6" rim with 4" back space. I have good clearance with front fender when turning.
The tires used firestone firehawk indy 500.
