ProtectoPlate Question
 

I have always been under the impression that the metal portion of the ProtectoPlates was stamped at the factory, and then the dealerships would add the Dymo-tape showing the name & address of the original purchaser along with the date the vehicle was delivered to the original purchaser. Someone else recently told me they thought that even the metal portion was stamped at the dealership. Does anyone know for sure which it was?

I believe it was all done at the dealer

How did the dealer know all the date stamps of the engine, trans, and rear? Did GM supply them with that info? Was it in a computer back then?

When I owned the orig. 67 Pace car I found just a bare Protecto Plate in the glovebox. It had been stamped but not in a warranty booklet.

mq. L78

On my 1970 Camaro (which I bought new) I have a metal plate stamped by the factory, and the dymo type plastic tape stamped by the dealer, & stuck to the metal plate. However, I have a1965 GTO with a smaller metal plate stamped by the factory, and another separate
metal plate stamped by the dealer. The GTO was one family owned before I got it.

Beginning in Aug or Sept of 1969 the factory affixed Federal compliance decals were imprinted with the VIN using the POP through a type of transfer like the old credit card rolling imprinter - The date in the upper right is a slightly larger size and wouldn't change except by the month.
Some of the compliance stickers have at least part of the Suffix codes from the engines and transmissions visible. (as Illustrated below)
(in the photo below you can also see part of the ink ribbon transfer in the center under General Motors)

The clear overlay was applied when the blue decal was affixed in the door jamb.

Are there any MQ's built prior to 0303

I think grumpys car was the same date. This is the earliest date I believe
