Dodge Challenger, Plymouth Cuda 7”, 8” 10” wheel widths. What fits?

Showing my 7”, 8”, and 10” REAR wheel widths. 7” wheel has a 4” backspacing, 8” wheel has a 4-1/2” backspacing, 10” wheel has a 5-1/2”backspacing. A 275/60-15 will fit a stock E-Body wheel house on a 7” or 8” Rallye wheel without offset hanger mods. 10” wheel with a 5-1/2” backspacing will fit with a 295/50-15 tire if you move the leaf springs in 1” on each side and use a 68-70 width B-Body rear end. A 10” wheel will fit your stock width E-Body rear end if you REWELD each spring perch 1” over AND use an 1” offset front and rear hangers. Also show my modified sway bar plate to match the stock rear sway bar width. I have 3 E-Bodies with 68-70 B-Body width rear ends in them. I am switching my 70 back to an E-Body width rear end because I didn’t like the gap behind the shiny trim ring on a Rallye wheel and Wheel Vintiques is offering a 6-1/2” custom backspacing for $15 more. The offset spring hangers have to stay and moving the perches in are needed.
