85 Iroc cast iron disc brake prortioning valve needed

I'm desperate for this proportioning valve The car has rear discs, the valve is cast iron like a drum brake valve but the inlets are different. Anybody got one?

Interesting. My 85 IROC has the alum version (which looks the same for both disc/drum). I would've thought that the old version would have been long gone by 85.

Iroccer, sorry for intruding, but the question will get you a bump .

dave mc, have you ever seen the first style on a car after 84? I thought most were gone by 83 with a few showing up in 84.

Yes but only a couple, I guess it might depend on when the car was manufactured
