how rare are power Brakes ?

Every DB A/F-body I have had or stripped out since 1970 had power assisted brakes. The only two drum brake cars I have had were not assisted.I don't recall how many that adds up to, but it is 45 years, so, a lot.

I thought about it.I haven't had that many A-bodies; 65-1,66-1,67-2,68-2,69-2,70-2,71-1,73-1,74-2,77-2,78-1,80-1
So that comes to 18 A's;2 of which were drum brake/no boosters,the 65 and the 66.

For inquiring minds; Valiant-1,Barracudas-7, Darts-2, Duster/Demon/Dart Sport-4, Aspen/Volare-4. Additionally I have owned a ; 57 BelAir, 71 Monaco, 64 StratoChief, 74 Pony, 84 D100, 92 Exploder,92 Dakota, 06 Allure/LaCross, 05 Escape, and I think that's it.
