If its stock and I think even if it is not, no worries about smog check to old. Atleast for now they don't mess with stuff that old. Everything I own is older than that except for my HD, I have not got anything smoged in years. I dont know for sure but I would bet most parts are get able, they were for my COE. Napa is real good if you can find a parts guy who cares and is good at his job. Think otherwise the parts venders have a fair amount of stuff. As been segusted try to have your paper work in order before you go to the dmv - their a pain under the best of circumstances, Good luck with your truck.
