The valve I ordered from GMPD finally showed up after 3 weeks, and since I was able to order one at work in 1 day, I don't need this second one anymore.
This is a brand new valve, never installed. It is designed for PowerMaster III equipped w-body cars. This is GM part # 88927272
You can get them from GMPD for $65 + $15 for shipping. I am selling mine for $65 shipped. Item will be shipped via USPS, so you'll get it quickly.
PM me here or email me webmaster AT lukez34.com if intrested.
