'73-up all A-bodies with front discs, plus some '74-up A-bodies with 4-wheel drums. On a drum brake car, measure to make sure.

Also be aware of the rear axle ratio and its effect on your car's performance (and your speedometer!).

9" front drums=SBP until 76
10"front drums=BBP 73 until 76

Not always! The "birthday cake" 10-inch drums were SBP at least through '74, and I've seen 'em on '75s, too.

take your tape measure with you is the best advise. I personally have never seen 10" brakes with SBP but I havent seen it all yet.

Definitely true.

Assume you mean you've never seen 10" SBP brakes on a post-'72 car. 10" drums were first available on A-bodies in late '64, and they were all SBP until '72. It's in '73 that LBP brakes started appearing on A-bodies.

I stand corrected.
Yes I did mean 73 and up 10" drums ( I have 10" SBP on the rear of my car now on the 8 3/4)
