15X8 Cragar backspace ??

-- Based on My calculations, on My 70 Duster, that will work. (8-3/4" rear - LBP) -- I'm in Florida, and heading back to Pa. the first week of March. -- I have a new set of 15" X 8" Cragars, with 4-1/4" BS, up there, and plan to install them with 255/60-15" tires, soon after I get home. Currently My rear wheels are 15" X 8" with 2" BS, and rub the lips. -- Those wheels are for sale. View attachment 1715144418
