Serial 46x14126 1964 model<br />Having fun stripped down to where engine and transmission meet. Engine now upside down soaking transmission in liquid degreaser along with 8 screw in bolts. Since transmission is too stiff to effect shifting need to get inside. The 8 screw in bolts appear to be original and of course are frozen.I entertain little hope of freeing them. Will never get enough torgue with screw driver to free and they will break. I can try heat but must wait until I can work outdoors as have a wife! Do machine shops have skills to remove?? Any suggestions?? I have the where with all to pay, but after too many times sticking with projects I have learned to abort when success is unlikely. If there were bolts I would be more optimistic.
