The software used to power this web site was updated on September 21, 2019. The update included migration of all content, users, and order information from the old site, so hopefully everything will continue to work as it has before. I've tried to improve the way search works, and I've added menus that help you find parts organized by manufacturer. Please contact us if you run into any issues and I'll do my best to fix things as quickly as I can.
I just added a new product to my inventory: a reproduction of the rubber shields used between the front bumper and stone deflector used on 1969 and 1970 Shelby Mustangs. We reverse-engineered an original shield to produce the most accurate reproduction on the market. Each set of two reversible shields is listed in our catalog for $20 plus shipping.

I recently added a kit to my inventory to rebuild the 1970 GM 1233464 metering valve. This valve is similar to the 1967 - 1969 3905525 valve, bit it doesn't include a large hex nut plug to keep the internal parts in place. The internal parts are completely different, too, so the kits don't interchange.

During the 1970s and 1980s Kelsey-Hayes supplied a cast iron combination (pressure differential, proportioning, and metering) brake valve to all of the major domestic automotive manufacturers. Here's an example that I removed from a 1979 Camaro:
I'm still working on a major upgrade to the underlying software used to make this site work. I believe everything is functional, but I'm still working through some display issues, including:
Things have been busy here recently! We've started exploring what's required to produced brake valve rebuild kits for AMC, GM, and Chrysler vehicles to expand our line of kits. We've also added a brand new reproduction parking lamp lens gasket for 1969 and 1970 Ford Mustangs that is simply the best available on the market today. Here are some links to our recent additions:
