in the process of changing from a ford to a Gm. If anyone has the dimensions on the engine mounts between the two prior to pulling the ford it would make things a heck of a lot easier. Grew up in the fishing industry but so far have avoided having to take on a major change. Spent thirty plus taking care of aircraft so some of the tools do fit my hands. Oh the trans is the merc MCM the outdrive is a TR2. thanks
