Hi guys, in process of restoring 70 GTO convertible that I’ve owned for over 27 years. Want to add a rear spoiler, but the one I purchased from NPD (local here in Michigan) seems really cheap and flimsy. They claim it’s fiberglass, came from the Parts Place....... Ames switched to a plastic injected version. Anyone have a suggestion as to who might sell a better rear spoiler? Looked for an OE but can’t seem to find one and car will be getting paint in a few weeks. Thanks for any help.
