Hello. I have a 1972 Grande with a standard center bezel set-up that I am replacing. Four screws attach it the bezel to the dash. I have the top two screws that attach the bezel to the dash just under the dash pad but I don't have the screws that attach at the bottom of the bezel to the underside of the dash. There are two holes at the bottom of the bezel and in the bottom of the dash. This is just under the heater controls. Can someone tell me what is the proper screw size is for the two holes at the bottom of the bezel. My bezel was removed before I started the project and I have tried a half dozen different screws but so far no luck. Hope you can help and many thanks for your assistance.
