Much thanks to haruman for the flex plate. I stayed at the shop till late last night installing the flex plate and I'm happy to report that after sitting 20 years this Montero runs and even goes into gear. Due to a lite schedule today I might even spend most the day changing the rest of the fluids and going over the brakes. See if I can get the Montero to drive around the block.
