VIN Rivets

[Z71]

Has GM used the Rosette Rivets exclusively?   I see 65't them but there are many who insist the regular pop rivet type was also used.  I-Car and some other groups say the Rosette was only from 1970 up.

So whats the story?  Who know for a fact?

I have seen several photos of VIN that had non-rosette rivets and the look original as the cars a baskets cases.  I know some have been installed from the bottom up but many don't agree with that.

My 67 RS and 70 Z/28 have the Rosette rivets. The 67 are in the door jamb of course and can be seen. The 70 rivets are installed unside down.

Thanks for the reply!

I don't suppose anyone with the rivets installed from the bottom would have a picture of the top of the dash and what the rivet end looks like installed there? 

Here is a a photo, could this be the blind side of the rosette rivet?



Does anyone by chance,  have any GM/Chevy etc documentation that references the type of rivets?

That photo shows the tool end of a conventional pop-rivet. Chevrolet started using the rosette-head rivet on VIN plates in 1965.

Thats what I was thinking also.

It look like someone forged a 72 Chevelle SS 454.  The W in the 5th position is for a 454 engine which could only be ordered with the SS option.

Chrysler is using a rivet VERY close to the original GM rosetta rivet.  John Z may know more about this.  I have a friend who works at the Chrysler plant in Newark, DE and he has open access to them.

Here's a '67 Corvette VIN tag with the original rosette pop-rivets; they're exactly the same as the ones currently being used by Chrysler products (I have two 2008's in my garage).

John,

I thought that to be the case.  You confirmed it.

Thanks,
