Howdy from Texas. I’ve just purchased a 64 series 2. It’s been sitting for a very long time. Previous owner put a 283 Chevy motor in it. I’ve got her running. I decided to jack up rear tires and try engage some gears. I have no pedal right now so just forced the gears. No grinding and no gears engaging. I took off the inspection plate and nothing is turning. The slave cylinder looks impossible to get to. Any thoughts.
