Andy, I have had about a dozen IH travelalls, PUs, and Loadstars. Due to rust none of them is road worthy now, but I still have a lot of the parts. I have both a 74 and 75 4x4 200 series. The limiting factor to the survival of these 2 years is the front brake rotors. They are unique to the IH line and went sky high in price (like about $850 - $1000 each last time I checked). The front axle is spicer and so some transplanting may solve the brake rotor problem. The power steering box is Saginaw (GM) and should be available as a rebuilt from somebody. The 2 most common engines used in both of those year 200 series trucks were the 345 V-8 and the 392 V-8. The easy way to tell them apart is the 345 only came with a 2 barrel carb, and the 392 only came with a 4 bbl carb. Both of these engines were of the same engine family, and look alike on the outside. They are both very tough engines that should go over 300,000 miles. The same engine family includes the 304 and 266 V-8s. Many school busses and Loadstars were fitted with the 304 and the 345. Internally they were the same in the PU and Travelall. The Loadstar and Cargostar series used a bigger oil pan and bigger radiator, but the engines were identical. Carb jets were different. If your 200 PU has the automatic tranny, it is the Chrysler 727, a nearly bullet proof tranny. Your transfer case is the NP 205 with gear on gear in a cast iron case (no chain and sprockets to wear out). It is probably the toughest transfer case available for the 1 ton and smaller truck. Your rear axle will be a Spicer 60 or 60 HD. Navistar is of no help in getting parts, but the aftermarket people have a lot of this stuff available. NAPA is one source I use. Dang good trucks, but the body needed to last longer. The engine and drive train would outlast the body in every one I had. And yes, they were very good winter starters. Just do not flood that engine, it is a real bear to unflood. Where in MN are you? Me...just a bit west of the Mpls metro area near Hamel. Stay warm... Paul in MN
