It ‘might’.
But on my 70 duster right now with 5x4 and that backspacing it would be maybe 1/16" away from the spring, if not touching. So I guess a LBP conversion might achieve a 3/16" gap between the spring and tire. All this on a 28x10.5. Right now I run 27 x10.2 on a 4.25 bs (sbp) and i have about 5/8" gap to the spring..
Regardless, it’s close a would likely rub under tire flex
