Yeah, I've been finding that it's definitely a one of a kind. I'm thinking of converting it to HEI so I don't have to deal with ignition boxes going bad and I may try to put a GM alternator on it off of an S10 since I have one of those under warranty at AutoZone. The main reason I bought the cluster is because the speedometer needle is bent because the magnet fell of and grabbed the cup; at least that's what it looks like. So I don't have a clue how fast I'm going, but the odometer still rolls over so I know how many miles are on it and that's how the previous owner kept track of how much gas was in it. I will say that the cluster I bought appears to be identical even though it came out of a 72 Duster according to the listing.
