quick question for the group. To switch from SBP to BBP, I need to change the shafts, drums and backing plates? brake internals the same or all of that too?
The strut bar that goes from one shoe to the other is different from 4" (a-body) to 4 1/2" (b-body) drums... The a-body one has a lengthwise bend and the b-body one doesn't...
It has to do with the shoe width 1 7/8" for 4" pattern and 2 1/2" for 4 1/2" bolt pattern... They have to put the bend in for the narrow shoe...
