Try ebay and type in GM Proportioning valve.. i have the same problem, i've called every source i could possibly think of and NOBODY has one

 

I have a new one in my basement. It's the 1LE design.
let me search....

 

I just ran into this problem myself. I haven't called napa, but no one else has them. I may just put an adjustable one inline after the rear section.

 

Autozone lists two valves for 1985 Firebirds, under the part name "Master Cylinder Kit" Part # 22232 and Part # 22351. I suspect one is for the 4 wheel disk setup and one is for the disk in the front and durms in the rear. I can't say that they have it in stock, but they indicate you can buy them on line. NAPA may have it also. So take a look and maybe you will be able to purchase what you need from them or another vendor.

i bought one from my local gm dealer about 6 months ago, brand new 1le. i would not recommend it though because of the preemo price you pay at the dealer for "GM" parts. i was just tired of searching for one and needed it yesterday, so i just got it there. i think it was something like $115 , which is absurd

 

look in the junk yard they are easy to find almost no one who grabs a disc rear off a car grabs the proportioning valve as well.

edit whoops sorry did not realize that you wanted a new one
