Were they just providing an adjective or is there really a separate Dodge gas NV4500 that is Heavy Duty?

Mel, I saw that note too, and I agree that it could cause some confusion. There definitely is a "heavy duty" version of the NV4500, and this is the one that was used behind the diesel and V-10 gas engines. The fastest way to identify it externally is the 1-1/4" input shaft. Even though Advance suggests that it can be used by swapping the bearing retainer, I think you will have trouble finding a clutch disc for it that would work on a GMC. The "standard" NV4500 has a 1-1/8" input shaft and that one will fit the stock GMC clutch disc.
