8 1/4 11" "A" body (only?) rear drums

I have a 74 Duster w 8-1/4 rear and it has 11" x 2" rear brakes. I saw a question in Mopar 'Action or Muscle magazine about that and in 74 there was shortage of regular duster size brakes and they substituted the 11 x 2 from Satellite. I got set of brake shoes at my auto parts store for 74 Satellite. My drums were ok with turn so don't know the part number for those.
