ya, i was also able to get most of mine at the local O reilly's, advanced auto parts, ect. lmc truck has 3/4 stuff so they might have 1 ton also,
but as BRENDAM M said "not to screw around with brakes"
the best word of advice is not to half-a$$ brakes put all new under it and it will be fine, and on my 49 3/4 ton it stops just fine having drum all the way around
