I haven't priced them, but 10" drums may actually be less expensive than 7" drums because they are far more common. Also, when pricing drums be sure the price is for two, not just one. Scamp
, for example, is very unclear about that.
Several years ago, when Dexter was selling to the public, I priced brake hardware (including drums) against a complete #9 axle
w/brakes, and ignoring shipping, the complete axle
cost less than the hardware (just as a complete brake plate costs less than the replaceable components). Had I lived closer to the factory, I could have bought the axle
, stripped the parts, discarded the axle and still been ahead!
