I posted in the N* Tech forum and they suggested I go to the Lindsay Cadillac forum to find Luke. Anyhow I need help finding the Water Pump Drive Pulley (plastic, approx. 4" diam., pressed on to front cam) for a 94 STS (see attached pic). I have tried my local parts stores, dealer and numerous hours online to no avail. If there is anyone that can give me a source or sell me this pulley it would be a huge help. Thanks.
