I am restoring a 66 glassmaster with a mercruiser 1 outdrive. I want to completely go through the outdrive and replace the seals,gimball bearing,bellows,gaskets,shift cable and I will need a gasket that goes between the outdrive and transom , which is the old flat gasket. Does anyone know where I can find these parts . I can probably have the transom gasket made if I cant find one , but I cant seem to find a web site that has the other parts that I need. I looked into changing to a later model outdrive but the bolt pattern is different and I would have to cut and redrill the transom. Since the transom is in good shape I want to stick with the merc 1.Thanks very much for any help. gmaster
