1967 GMC Super Custom?

[Field69]

Hey guys,

I'm wondering what I have here. I bought this truck from the original owner, it's got less than 100K original miles, and is completely rust free (nothing in the bed, rockers, front fender cups, etc.). It has super custom badges on it, but I've heard different things about the 67 super customs from only coming in big window (mine is small), the doors panels not being metal (mine are vinyl), and the mirrors being body color (mine are chrome).

It's been in California all it's life as well. Can anyone shed some light on whether or not this is a real super custom? And if so, what is this thing worth? Should I hold onto it, or sell it?
