Viper- Good clues, thanks! Can you give me a hint where I might documentation on this in '74 materials? I have a '74 Data Book but not a '74 Truck Facts Book. Don't have either for '75. I'll look more closely in the '74 Data Book in the meantime. There is a note about a "California Emissions Package" but I haven't found a list yet of what is include in that.
I'll say this to everyone: Please, PLEASE don't be offended if I don't "take your word" for everything and ask for documentary links. Perhaps not everything I write is 100 percent correct in the broad sense (barring my mistakes) but I can usually present documentation to back up my assertions. Perhaps I demonstrated that a little in this thread. Documentation is important if you are going to write about history that will someday be held up as a "fact" It's not so much if you are just a poster on an intent forum. I have been bitten in the butt too many times by not fact checking little details like this. More than that, I have learned the timeless value of getting things as right as possible. As a writer historian I have learned that among the hardest things to overcome are the incorrect facts laid down by a previous writer and now considered gospel by people who don't have access to the primary information.
Anyway, bottom line, I LOVE to be PROVEN wrong but I prefer to have that done BEFORE I put it on paper. That's why I like to find a good board like this and get my ass whipped a little.
