Sprint package does not include a nodular posi rear by default, and if it was on a Sprint car, it was an option. HOs had it with a 3.55 or higher ratio. I agree, Rob, that H most likely means something else. It could be hood tach. It could be the Heavy Duty rear suspension (nodular), which is most likely. It could be just about anything. If we pool our billing histories and manifests, I'm sure we can come up with the right answer.
