rear brake parking brake strut

All of the SBP 10” brake hardware can be used with the BBP 10” brakes. It doesn’t always go the other way though, some of the BBP 10” brake hardware doesn’t necessarily work with the SBP 10” brakes. I did a more in-depth write up on it I’ll see if I can find it
Thanks, makes sense, the sbp strut has the edge turned up probobly due to the narrower shoes/depth of drum.
