They sold you a misrepresented product, whether they knew or not, is a different story. As a SELLER they must know what they are selling, or admit that they don't.
They say it belongs on a 1994 Warrior, so they should make damn sure that it does. If they would have said "we think it's from a 94", they'd have a leg to stand on.
With that said, and knowing it's misrepresented, go to Ebay with it. It's a fraudulent sale. Also **** in their feedback, and out them as a seller here. Let them know of your intent(in a non-threatening manner).
I bought a new DG, and it was a bitch to get on, but it worked. Yours, no chance in hell.
