Mushy brakes 4 life...
Checking back into this one with some measurements from one of my 11x2.5" brake set ups.
From the drum, inside friction surface
Depth. I know I show the tape measure here, but I also measured with a set of calipers- 4.46" to the outside
This where it gets a little more interesting. This is a set of Dr. Diff BBP axles in a stock A-body 8 3/4 housing, using tapered bearings.
That measurement is 2.3", also checked with calipers. Now, that's with tapered bearings and this is the passenger side, but these brakes work so...
I think this is the measurement you really need to take. Face of the axle to the outer lip of the backing plate. The square is in tenths on the side being used, FYI, so, this is about 3.45". That's off the mounting surface, not the register.
And last, in the thread where you ID'd the backing plates I never saw a diameter of the backing plates posted. Did you measure it? The 11x2.5" backing plates are ~12" in diameter measured to the outside edges.
