A little bit of research on Ebay will turn up massive quantities of original equipment brake linings, rivets, and even some specialty drill bit/counterbore tools to make uniform depth holes for the rivets if you opt to buy generic brake lining material on a roll and drill it to fit your brake shoes. I know of at least one one bolter with a professional-quality brake lining riveting machine, one that probably hasn't been used in a few decades! It's not that hard to install brake linings (and clutch facings) with a ball peen hammer and a punch, though!
