      If you want the wheel centered in the wheeltub, it takes about 8.8" backspace which may be tough to find. That backspace is from rim edge (+.5" each side), not bead.

      A stock A body 8.75 rear with BBP conversion uses ~7.75" backspace 10" rim to get them under the car.

      I have 10 inch wheel with 7.5 BS 295/50/15 tires on mine. The rear tires rub on the lip of the wheel well. Probably have 2-3 inches of space to the leaf spring though. B Body rear end also.

      You guys should also list which year B body rear you have like Kim did. The B body rears vary in width by a few inches depending on the year, so that could make a significant difference in backspace.

      Housing widths, flange to flange:

      A BODY
      '66-'72= 52 5/8"

      B BODY
      '62-'63= 53 1/4" (And '64 Max Wedge)
      '64 = 55 5/8" (Exc. Max Wedge)
      '65-'67= 54 1/4"
      '68-'70= 54 15/16"
      '71-'74= 57 7/8"
      '71-'73 wagon= 59 7/16"

      I have a 67 rear in mine with an 18x12 and 9.1 bs. A Demon/Duster could get away with less bs probably in the neighborhood of 8.25-8.50 since they don't have to tuck inside the wheel lip.

      I do not know the year or vehicle it came from as it was already in the car when I purchased it.
