I was looking at the sticker in the glovebox of my '71 to check out the options the truck came with. One caught my attention. It listed a steering stabilizer. Right now the truck does not have a steering stabilizer on it, nor does it really need it since it handles fine. I was wondering why it would have come from the factory that way. Perhaps it was part of the heavy duty package? This truck did come with heavy duty front and rear springs, heavy duty shocks, and the auxillary leaf spring. That's the only thing I could thing of. Any ideas?
