Hi,
I'm not quite sure, but I think that'73 was the only year that they didn't come with cats, maybe '74 too. Ithink after that they were required by the government to have them. Up here in ND, though, I would say that over 90% of these older trucks have had the cats removed by their owners. I know that mine started on fire and had to be removed 19 years ago... I'm not totally sure on this, but that's how I remember it being, there might be exceptions...
