rear shoes for 1968 polara 2″ ?

So I recently installed a 8 3/4 rear end out of a 1968 polara into my sons 1956 Custom Royal
it needed new brakes so I ordered some from rockauto.
I could not find any 11 x 2 shoes so I went with some that were listed as not for heavy duty brakes but they did not list the shoe size. The shoes that came off of the car were 11 x 2 The ones I got were 11x 2.5.
Question did any c body cars come with 11 x 2 rear drums?

I posted some pictures for reference.
Also what cars did come with 11 x 2...
