GMC c7000 Kodiak brake probem
 

Hi..does anyone have a picture of brake setup and part number for the shoe adjusters that attach to the rear back plate on a 1982 c7000 gvw 23160 366 v8 dump..? They are riveted on and the replacements bolt on. I dont have a part number but the cylinder numbers are FD-24491 Wagner -Lockheed..there are 2 adjusters on each side..the brake shop is claiming there 200 each..I feel like its a bad dream..
