Re: 1966 GMC 1 ton Dully rear drum
The availability of New Drums is great news. For many, many years we had to rely on good used drums only. I even know of many who swapped out the whole rear to the newer style because those drums were that hard to find.
I would have to verify it, but I always knew the interchange to be '63 to '70.
