Wanted- dually or dually parts

[Tx Firefighter]

I want to build a dually truck. I only want the short wheelbase one though, not the 157 incher.

I'm looking for either suspension and brake stuff or I'd buy a whole truck if the deal was right.

I have a trailer and can travel a reasonable distance. I'm in far North Texas, so Oklahoma, Arkansas, Louisiana, or maybe even lower Kansas is in reach.

Tell me what you have, no parts too big or small.
