GA WTB: Brake Distribution Block/Pressure Switch and Bracket - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**IronCanine** · 01-20-2024, 11:22 PM

I'm looking for the distribution block/brake pressure switch and bracket for a drum/drum truck. The part number is 3923719 for the switch and 3906551 for the bracket. NOS would be great, but would be happy with a good condition original. Biggest thing I'm looking for is minimal to no rust. The ones I have are too crusty. '69 and '70 should be the same. 10/20/30 all should be the same. Manual vs. Power also should make no difference.

Thanks for looking and hopefully for having.
