Are the 70-72. 9" brakes the same as the earlier A bodies ?

Think they have a wider shoe, at least on the front Drums vs like a '67.
Not sure...

These drums are wider than I was expecting. So you may be correct on that. I wonder if with the matching knuckles that I got with em it will all change overto the early As.
Pretty sure the 70-72 spindles take the small ball joints.

'72 and earlier 9" drum brakes all interchange. The '70-72 version has finned drums. The hardware kits changed late '60's too when they went from shoe retainer springs/clips, to the Bendix type pin/spring/washer type retainers. There were other changes in hardware too, such as self adjusters, but, if you include all the parts of a given year, they will swap no problem. The later setup is a superior design however.....at least as much as a 9" brake system can be called that.
