Brake drum interchange info, again!

I asked this question before, but have misplaced the info.
What year brake drums will interchange with my 49 Olds?
The drums are 11 x 2.

 

fronts 49-56 88-88A-98
rear 42-52 78-88-98

 

There's a place in Wilmington, CA called the Drum Garden that makes brake drums for everything and pretty damned cheap too. C.H. Topping turned me on to them.

 

Thanks Crestliner.
