Yeah, that's what I expected to find, but I tore the back brakes apart and found that my truck has the Hucks on the back, too. For all I know the truck may be a 1950, though the title says 1951.
That link I posted has shoes for the Huck rears as well as all the other parts you might need. The part for the shoes is MEB515. Just be sure to tell them the year and type. If your shoes can't be relined, you can get replacements through Jim Carter's, but you'll have to eat the $100 core charge.
P.S. Just edited this post to mention that the MEB515 shoes are on back order.
