I think I am going to pull out the engine and trans as a unit. Seems to be a good approach in that I really am looking for the most straight forward method of getting to the flywheel. The step by step is in the engine shop manual I have for the car. Probably need to check engine mounts, and maybe rear engine seal while I am at it. Hoping that a weekend is enough time to do this, probably won't get to it until weekend after the one coming up. Will line up parts, etc., in the meantime. Cheers, Don
