I don't know a whole lot about this truck because I just bought it last week. I do know it has a 534SD gas engine a 5-speed mystery hurst shifter with a split rear end and a PTO pump that controls its 12 hose hook-ups. My cab is a bit complicated to tilt up it has an electric hydrolicpump with a piston mounted near the front that tilts the cab up. It only has 16,753 miles on it and the lights and sirens all work. the engines runs like a dream after warming up. My first and only question for now is where can I find engine parts? what companies sell parts for that size engine? Summit Racing, who I usually order parts from for my two 69' Broncos, 66' Mustang, and 74' 4WD Econoline, does not carry any parts. If someone who reads this knows of any companies or places I can find parts for it please post them and let me know. Thank You.
