8 3/4 springs on the cheap

I had some slot mags on my car from back in the day that worked with some pretty wide bias ply tires; don’t remember the specs. When I went to radial T/A s I had to change wheels. I found 4 1/4 to 4 1/2 backset centers the wheels in my 1970 dart.
Yep! 15x7's. I wouldn't try 8" wide. Too close with out trimming.
