The links you posted look like they are for the engine only... If I am buying a car I am concerned with a lot of other parts too.
Sorry, you're right, and you should check everything. I was completely focused on the drivetrain, because with this rig the drivetrain is everything. If it's perfect, everything else is a small detail. If it's bad, the whole thing is scrap. Truck is 18 years old.
You going to go look at it?
