98-00 had a differant spec cam than 01-02, but 01-02's had the ls6 intake w/o egr. probably a couple other small things im missing, but thats the popular one.

what kind of "kits" are you talking about? that may help us.
most likely they are interchangable. but things like emissions hookups for headers would be different.
another thing that changed was the size of the injectors, not sure when or how though.
and also some 01/02 were the LS6 block....but everything else is the same...and should not affect what bolts on

oh...stay away from the SLP kits...
they are overpriced for what they claim the yields are (which are exagerated anyway).
tell us what you want...and we'll advise you on what to get

Was 99 the only year that the temp gauge was faulty, or were 99-02's all this way? Some of the differences listed above make me feel good about having a 98!
...and yes I am lucky enough to have the steering wheel buttons.

You mean steering wheel controls? I thought steering wheel controls weren't available until '00, on Camaros at least.
