NAPA has shoes to fit your truck (UP299R).
They also have return springs 80163 (set of 4) and the adjuster spring @ the bottom that holds the 2 shoes together 80518 (also a set of 4).
New, made in USA wheel cylinders are available from Dorman as W18010. Same for both sides. I bought mine on Amazon.com.
The 14" x 2-1/2" Bendix brake was used up into the 80's in the Chevy truck line.
Looking for a company advertising "industrial frictions" will usually get you to a place that does relining.
