sbp to bbp
"Depends"
SBP and BBP use different flange offsets...
BUT, there are aftermarket axles that use the SBP offset but have the 5x4.5" pattern. So, if your axles are BBP and have the BBP flange offset, you need new brakes. If your axles are BBP but have the SBP flange offset, you have to re-drill your drums.
