Certain parts I would be weary about getting custom with no one backing them.
This was the primary reason Amazonica went with the BR6 parts, rather than the Teraflex BBK. Her reasonng was Chrysler would most likely have stock where an aftermarket outfit, maybe not. I really wouldn't worry too much about either Dynatrac or Teraflex folding any time soon. The Ram 1500 option is a good one as well, provided you or a local machine shop can fabricate the required caliper support.
The TF BBK caliper is essentially same as the Ram 1500, uses the same pads. The rotor specs do not as I recall match up exactly.
