Just bought a 1991 Service Manual for D/W 150-350 with a Diesel Engine Supplement for $70 + $10 shipping on ebay. Thing is - I don't need the Diesel Supplement. It's in great shape! I can help a fellow Dodge brother out with a steal of a deal. How about $25 and I'll even ship it. PM me if you are interested.

This manual covers the 5.9L Diesel engine, brakes, cooling system, instrument panel and gauges, speed control system, wiring diagrams, exhaust system and intake manifold, fuel system, steering, transmission, air conditioning, and emission control systems.
