Greetings, I have a 1976 Chevrolet front body with power steering box that is connected to a newer LS1 motor that both ends are different. One is metric and the other is not. Does anybody know of the situation and where I might be able to find one? It came off of the high pressure connection fitting and the owner doesn't want to put on any type of clamps because of the possibility it might come off. I do have an idea of how to fix it so it might not but if I can find one somewhere that would be great. Thank you, Doug
