wheel spacers

70 E-body with a .080" spring relocation. I think i might need just a little bit more spacing from the leaf as well as the factory wheel tubeView attachment 1715308750
This pic is with my old SS Spring and a 26x10 slick on a 8" rim
have new rim that are 10" wide and a 28X10W x15 slick i'm trying to shoehorn in without modifying the factory tubs or wheel well opening.

my math says it will fit but i might have to cheat it with a 1/4 or maybe a 1/2" spacer.
10" wide wheel with a 7.5" backspacing.

I shoe horned my tires in too, I make my own spacers out of what ever alum. sheet I need .
