Actually Murray B.Park at www.cbodies.com is the one who told me that from his searching it was only nine 4speeds with the 383 Monaco 500 made and only one 4speed with the 440 Monaco 500 in 1966 and he has that one.He's located in Ohio but he was at Carlisle this year and a buddy of mine told him what I had and he gave him my number and he called and told me that it was a rare car and only nine of them but I hadn't been able to get in contact with him again to get some documentation
