69 Charger Spindles

So I have a set of 69 Charger DRUM brake spindles around. Could I use those on my 71 Dart if I change my ball joints and other supporting items? The articles I found on Hot Rod and even on here talk about the E-Body and late B-Body DISK brake spindles being used but no one seems to have talked about using drum spindles. Reason I'm looking at this is there are some nice big brake kits for the b-body drum spindles that just aren't there for the A-bodies.
