Jim Saw this web site and thought you might want to get one of these for your GSX. Now tha N.C does not require inspections for classic cars you can use a vintage sticker. http://www.roberthoyt.net/Inspection.html
I can remember the first truck i had in NC was in 1976 and we had inspection then. Sure is nice that they did away with it for the old cars although i do get a few hard looks from some local police.
My family is originally from NC. As far back in the 70's as I remember, their cars all had inspection stickers on them.
