what years can i get 11x2 drums from

[BubbaCuda]

I installed my backing plates that i bought off ebay. They were suppose to be 11x2 brakes off of a 72 d100.. it just seams that the drums fit to loose on the studs and the drum area that contacts the pads seams much wider then the brakes that are 2" wide..Do i have the wrong brake drums?

Are you sure that isn't a 2 1/2 inch drum setup?
