10 inch Brake Backing Plates - Simple Source?

And then there's these. This is the list for 11x2.5" BBP drums. Again, probably not all inclusive, and with these sometimes you'll find they have 10x2.5" drums as the 11" drums were an option on some.

The 5th Ave's and Diplomats are great sources. The van's on this list almost NEVER have the 11" BBP drums, they mostly used some 9 1/2" drum that's pretty much useless. But the 11x2.5's were an option.

Also, not on this list are the heavier trucks that used a 5x5.5" bolt pattern. The 11x2.5" brakes and drums that ran the 5x5.5" pattern are the same as the 11x2.5's with a 5x4.5" pattern except for the bolt pattern on the drums. So, the backing plates and everything will work, you just need different (or re-drilled) drums. Just the 5x5.5" pattern though, anything with an 8 bolt pattern is a no-go.
