Are the brake shoes the same ?
I've seen DJ3A shoes that look the same but have 1 3/4" friction material instead of 2" the Aero takes.
One rear set I disassembled from a parts car had three 2" shoes and one 1 3/4" shoe. They were nice vintage Bendix shoes with brass particles embedded in the material. I was going to re-use them till I saw that odd shoe. Ended up having my original set relined instead, still sitting on the shelf.
