I recently removed a pressure differential valve/distribution block (see attached image) from the left front frame rail of a 1970 Impala. I'd like to understand if the same (or a similar) valve was used on any other Chevy or GM vehicles. The InlineTube web site (Product Info) lists several applications, but the valve body in their picture looks a little different than the one attached here.

I'm asking because my company (see my sig) is in the business of producing rebuild kits for a small number of brake valves and I'm looking to expand into GM applications. This valve can be disassembled and I can provide the parts to rebuild it, but I need to confirm two things first:

• Original applications, and
• Interest - are people looking to rebuild these valves?

Are the applications listed on the InlineTube page correct? Would you be interested in a rebuild kit if cost approximately $20 - $25 or less? Do you know of other brake valves that might be worth rebuilding if a kit were available?

 

I just finished posting an article on my site that describes how the valve can be disassembled:

A rebuild would require clean up, replacement of the seals and springs, and reassembly.
