Replacing Fiberglass Nose Piece GT350

Does anyone have any suggestions on the best quality replacement for the fiberglass nose on a GT350? Have tried a couple of aftermarkets and am having trouble with the fit along the top of the fenders. I would like to know if there are quality suppliers for best fit. The noses I've tried fit fairly good with the side fender lines but are approximately one inch low from the top edge of the fender. This requires major fiberglass rework due to molded structural support on the mounting edge of the nose piece.
