Hello. I have a 1972 Grande with a standard center bezel that I am replacing. Four screws attach 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 right screws that attach the bezel at the bottom to the underside of the dash. There are two holes at the bottom of the bezel and at the bottom/underside of the dash. This installs just under the heater controls. Can someone tell me what is the proper screw size 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 so far without success. Hope someone might be able to help. Thanks for your assistance.
