MIC - Manual Air Valves

I've been running 3/8" MIC Manual valves on my truck for 8 years now with little to no issues. Recently I hunted down the guys at MIC and appearently they only do installs now and misc. parts. They stopped carrying the valves and the rebuild kits for them.
 
Of course as I bring my truck out of winter slumber last week I notice one of my valves is leaking pretty bad.
 
My question is.... does anyone know of someone who might have an MIC manual valve laying around somewhere or even better a rebuild kit for the valves? Otherwise I'll have to make a run to a specialty plumbing shop to get seals and gaskets.
 
thanks
 
 

somebody said on another forum I think that the guy who used to make these is the owner of go ez customs but im not 100% sure I just remember somebody talking about it.
