Front tire clearance : what rim / BS on a 1970 Duster?

Car is a 1970 Duster with a 383, 1" torsion bars and pst sway bar.

Hi,
The rim I run on the duster have been given to me by a friend, they were on a 1971 Cuda before and guess what, I have a clearance issue with the front wheels hitting the rear part of the wheel well.

I had a look to whats written on the rim to know their specs but I'm not sure to understand.
I measured the backspace but I can't link the value I found to what I read. Could you help and tell me if I need to order two rims with more backspace at the front?
