How fast would you like to go.

Lol, run what you brung! Those rear rims were on it, just like that when I got the car many moons ago. They are Weld wheels, from what I know (ain't much). They'd be sticking out mighty far, if I turned them around (if that's even possible). That's Torino?, or medium bodied Mustang rear, IIRC. Thx for the tip tho, lol. Maybe it's time I got real glasses;

No worries Lefty, I was just curious. (They still look like Cragar Supertricks to me! with a weld racing center cap). I have seen it done, for the exact reason you stated. With them mounted as built , the tires would stick out, or hit the fender.
If you want to know, pull one off, and look for another valve stem, or a plug, on the inside half.
