Check the VIN number and your original spec sheet if you can. Each truck has all the information listed on this to give you information. My research took me very deep in to "my chevy" and of course it has even more sentimental value so I went into extensive detail. Including that call I made to the Chevy factory's archive department.
I check out various websites including this forum on a regular basis although I don't usually get involved or comment. Here are some of the ones I follow:

I didn't mean to start a controversy. It is just interesting to walk through a "classic car show" and see the various trucks passed off for what they are and in all reality aren't and I just usually shake my head and walk on.
We all own an awesome piece of American Cultural History and when all comes down to it...
It's a Classic Chevy and our PRIDE and JOY!
