1958 GMC Carpenter CorsAir Bus-RV Air Brake upgrade PARTS needed
Hoping someone in community can help me with this upgrade from 1-Circuit (1 air gauge on dash..) to 2-Circuit Air Brake system - I need parts: (a) 2-Circuit Treadle Valve; (2) Spring brake - park &/or emergency activation know on dash (old "level" vs. "old blue/black" vs. modern "yellow know" - idk which is best, yet..); (3) Several Air Brake Relay components (R12, R14 Air value or Spring Brake Value.....); (4) DOT-approved Air Lines for plumbing this & lastly, my (5) two new upgraded Maxi-Brake 30-30 Serv./Spring brake Air Chambers on rear.
-Best place to get these parts (I like Bendex or Haldex but what do I know?)
Looking for idea, suggestions, websites, help....
Many thanks in advance
