If you need the best wrench in town, Give Jimmy Allen a call at Allens Automotive in Kendall Park.  They are the ONLY guys to wrench any of my cars.  They are all SAE master mechanics and all muscle and Vette guys.  Theres a line of old iron out front all the time.  Drop my name, he's a bro..

a place you surely should take a look is inside of the doorpillars , the bodymounts in it , and the windshield frame is also as place rust often eats away ( actually it is best seen when you take the chrome molding on top off.. but from the inside ( unscrew the molding can give you already an idea)

both insidecorners of the frame infront of the rear wheels can easily collects dirt and water , meaning rust will do it's job there.

and don't forget.. rust is always worse then you might think at first sight
