I saw 2 of these on ebay and placed a bid on them anyway. I won the bid and got both for $60.00. I was not sure if I had made a wise move but the package arrived today. They look almost brand new and the base is exactly the same size as my rochester. I found out that they came off a 6 cylinder 226 jeep super hurricane engine. I will install one of them and see what happens. I hope I hit the jackpot.
