Can anyone tell me if there is a difference between the '68 GTO and the LeMans front fenders and hood? One spec sheet I've seen shows the LeMans total lenght 4 inches longer than the GTO. I have a '68 LeMans Convertible that has been cloned into a GTO. The endura bumper does not fit worth a crap. I know its a bad fiberglass reproduction, Ames says they won't sell them till quality improves. OPG is now making a new rubber endura for lthe '68-'69 models that is suppose to be an exact copy of the original. I'd like to know before spending big bucks on it if it will fit, or are these LeMans fenders longer? Anyone know for sure?
