Abody SBP 7&1/4 vs 8&3/4 SBP overall length

is the end to end wheel flange distance pretty much the same for the two? I'm swapping rears & having potential wheel backspace clearance issues from wheel/tire to leaf springs. I am not in a position to measure everything right now. any thoughts? thank you for your time. RR

The short answer is, no, they are not the same width.

I don't have information for the SBP 7 1/4, but I know that the BBP 7 1/4 housing is only 51.5", vs the 8 3/4 which is 52 5/8". So if the SBP 7 1/4" housing is the same width as the BBP, the SBP 7 1/4" is narrower than the SBP 8 3/4, and the difference will be more than a 1/2" per side.
