Found a Source for 10” rear drums with 1-3/4” shoe

Thanks and a tip of my hat to g413, I had just about given up on ever finding 10x1-3/4 drums when I stumbled on this post while looking for something else, go figure. I took a chance and ordered a pair in spite of their being listed by Centric as front drums. They arrived today and they are dimensionally perfect. They look to be better built than the OEM's, are a bit heavier, and certainly have a nicer machined finish. Our local auto parts sells Centric and this number doesn't exist in his catalog nor on the warehouse website.
This forum is the best, and an amazing resource.
