im sorry yea that signature is misleading it is an RS but it has a body kit that made it look exactly like a z28 so we put z28 emblems on it....i need to specify that but im too lazy...as for the air cleaner lid i just painted it myself and i also figured that the pictures wouldnt be good enough to tell anything. the only other thing that i know is replaced is the alternator because i just put that in myself as well. oh well maybe ill take it to someone just to make sure that i really am gonna get that 100,000 miles out of it that i was told.
