Good Answers! I can actually jack the engine up by this bolt! Its fangs are embedded in the 1/8" steel engine plate thing that supports the engine above. Yesterday, six hours of fooling with the darn bolt to no avail. I am a patient person, but probably a little too much so. I sure hope I don't have to lift the whole godverdomme

engine out just to replace the front mount! I have just come back from shopping at my auto parts store for the ultimate weapon - an air hammer.
Armed with this and Truck'26's verbal Dutch tools, I may get somewhere today. I will report later.
Thanks all!
