Another 11" brake question...

Looking for parts for the 11" brake swap.

On the howto in the tech section, it lists NAPA part # RBP AE10AR for the shoes. This set is $41.49.

But if I search for a 1972 CJ-5, I find these 11x2" shoes as well, for $14.99:

Someone know why the huge price difference? I'm looking for cheap here, and if either will work....

 

could be grade/type of lining used
also bonded vs riveted lining

 

K. Well I'm going with the cheaper shoes, they're easy enough to upgrade later. Will be a few years before I even drive this thing, right now just trying to get this front axle back together. Thanks.
