1968 A body 10" x 1-3/4" brake hardware?

My point for the OP was not to mix the adjuster components. If its set up for the early, then stick with it or change everything.
I've used both systems and had no issues with overadjustment with either. The tabbed shoes are supposed to reduce chirp. Again not a big deal, but something they wanted to address. Shoes using the 256 and 288 frames (aka webbing) are rarely available. Instead the 151 or 331 frames are generally substituted.
