You mean the new drums were stripped? Are 67 drums one piece or 2?

I'm gonna assume you have 2 piece drums and the part that is stripped is 
the hub, not the drum.

I think they could be fixed with a Helicoil if you could find someone who had 
the Helicoil tool in that size. (I wonder if it is the same thread as a spark 
plug???)  Otherwise, I have a good used hub.

The only other time I have seen someone strip out the hub holes was when 
they were sold some Brazilian replacement hubs which were cast in one 
piece. In that case the cast side flange on the replacement was considerably 
thicker than the OE part, which has a cast-in steel side flange set in the cast 
iron drum. The thicker flange kept the OE bolts from engaging enough 
thread, and the hub eventually stripped. If this is your problem, I would 
recommend that you return the drums with your complaint that they are 
unsafe, explaining why, and should not be sold unless they have longer lug 
bolts to sell along with them. Of course this can also get you into trouble, 
because if the bolts are TOO long they can hit things inside the drum and 
destroy your brakes.
