this is my buddies truck that we built. he is 6'4" and the tires are 52". its a 65 international, has a big block IH.

 

When we check vacum lines we start checking them where the hose clamps are or the spot with the most bend. If it is the vacum lines its an easy fix easy to check them to we just buy a can or two of starter fluid and spray a litlle as you work your way around if it revs up you found your leak. i hope it is the vacum lines i wanna see some videos of that thing in action. 02dirtyd that is an awsome rig and the old international cab probably is stronger then most newer trucks with the roll bars i should go pull one of the cabs outta one of the old ghost mines and build on up like that. 52'' tires forget a boat id drive that up the river duck huntin

 

Haha ya it's a big truck, I wish I could find another one to build.
