Research Topic: Sill Plate Rivets

Were you lucky enough to find New Old Stock (N.O.S.) door sill plates for your Chevy II or Nova? Ever get points taken off at a show because the later GM door sill plates did not have the little rivets holding the tag to the sill plate? The Nova Research Project is still researching when GM stopped using the sill plate rivets. Until then we have found the correct style new rivets to add to existing sill plates. See below.

Research Goal:

Determine when GM stopped using rivets to hold the Body by Fisher coach plates onto the door sill plate.

Do you have an original 1971 - 1979 Nova that still retains it's original door sill plates? If so, please send an email with the following:

Does the door sill plates have rivets or not.

The VIN (We use this for indexing and date estimates. Really helpful if they changed mid year)

The Body Number? Same as VIN.

The date code off of the trim tag?
