Looking for a set of new reproduction 11 X 2 drums for my 8 3/4 rear end. Can't seem to find any. Does anyone reproduce them anymore?

I've read a million internet posts about them being on certain B bodies or C bodies or trucks but when I check on Rockauto or in person at the local auto parts stores, I only find the wider 2 1/2" drums which I can't use. I've wasted weeks searching every possible combination of make, model, engine size, etc. trying to find them.

My belief is they probably used these drums in a bunch of applications but stopped making them because people were only buying the 2 1/2" drums which were typically offered either as standard or a HD upgrade in various models. And since they stopped reproducing them, I'm guessing the automotive search options for these narrower drums fell off or were deleted so you can't even see them anymore.

Anyone else go through this recently and found an available substitute? Yes, I know I can stick with 10s or go with 11 1/2s but I already have these backing plate assemblies and I was hoping to use them if I could.

Not that I would run 11x2, but rockauto has them.
I would look for better quality than centric.

Looking them up by number, the specs say these have a friction surface width of 2.59" I've been interpreting that as a 2 1/2 shoe. Guess I could roll the dice and try them.

If you read the spec for the 2.5 drum, it lists the finished surface at 2.93.
 The listing for the posted drum says not for wagon, so thats sedan at 2"

I wouldn't have any issue running that brand.  I went the other way, I have 2.5" drums on the back, but use 2" shoes to reduce surface area and eliminated my rear lock up issue without adding a proportioning valve.  This was after reducing the wheel cylinders.  The front brakes do 75% of the braking, you don't need much on the back.
