    Thanks gdmjoe. I found those but they say they're for Lincoln Town Car. The Ford part number for the Marauder RAS comp (4W3Z-5319-AA) is completely different from the GM & TC (8W1Z-5319-A) so concerned a wiring difference or something making it not work or cause damage. We used to have the part numbers on the site but got tired of reading dozens of archived threads. TY

    I replaced my compressor with whatever I could find on rockauto a couple years ago and it's been fine. 99% it's all the same actual part

    I've used a Marauder compressor in a crown vic, and a crown vic compressor in a Marauder. I wouldn't be surprised if the only reason the part # changed is due to the little "muffler" they put on the inlet line for the compressor.

    I emailed Arnott & Suncore.

    Suncore says they have no part, I then find a Suncore on the Suncore eBay page listed for the 03/04 Marauder, I send the link back to the Suncore rep with a big what the heck, he scratched his head and said I have no idea.

    So ordered the Suncore off eBay, installed Saturday and works great.

    Incase anyone needs this in the future:
    Suncore 40F-20
    Arnott P-2936

    Good to know...just ordered the Suncore one myself. Mine **** the bed Wednesday and it was OEM. Pretty good price for the Suncore, so seeing that you have used it/works well that makes me happy!
