I bought the 1969 OER dash pad. I honestly threw in the trash as it was way too late to send it back.
To me , the most obvious flaw (hindsight 20/20) , the OER pad does not have the metal skeleton required to install the instrument cluster. It does have the oval holes for the plastic nuts , but there is nothing there to hold the nuts in place. Also its vey flimsy and the fit is below OK. I attempted to make a tin frame and make it fit . After a couple of years of hating it , finally just tossed it in the trash and used my best OEM dash pad .
