I have acquired several parts vehicles for a 1 ton 4x4 I'm building. I have one Turbo 400 from from a 1990 Suburban mated to a NP241 t-case, and another from a 1985 military 1 ton M1008 mated to a NP208. The one from the military truck says "HD" on it. Is there such a thing as a "Heavy Duty" Turbo 400? What is the difference from a regulary Turbo 400?
