'70 A body 10" x 1.75" Brake Drums NEEDED

I have searched extensively for new ones. I have seen them for $80 used on ebay. A rockauto listing showed them (depending on interpretation) for $25 ea, so I bit. Turned out they were the common front drums, (got plenty of those now). I don't currently need rear 10" drums, but when I do I think I will either cut the lip off some single-lip fronts I have (looks like it would work) or buy ones for BBP and drill new holes. Perhaps by then Centric will get wind and pour some. It seems that happened for the K-H front disks that were very expensive 5 years ago until Centric stepped up.
