Thanks for the site.
I actually seen you post that site earlier when I was searching through old threads. Going to see if I can find one cheaper that is used first. Then buy new if i have to.
I need to sell the one I have. Or trade. I have the newer one, 89-92. Found that out the hard way today. lol

Re: Need Disk Brake Proportion Valve 1st Design
I had a similar problem after I had my rear swapped in the 89 vert.I pulled a disc prop valve from a 90 formula 350 and it would work.Luckily I had also purchased one from thomas at house of camaro which was from an 89 iroc and it fit.The brakes now feel 100% better

Just a note: All four-wheel disc cars, 82-92, are RPO J65. Only the 89+ cars, however, will have the 1LE-type combination valve (and there are two designs, first and second). When you mentioned first design, the above is what came to mind.
