Default PHS question for 68

I have a friend that has a 1968 GTO convertible and has received the PHS documentation for this Baltimore built GTO. For some reason the engine id and the transmission id both are showing all zeros in both locations. Has anyone ever seen this before and if so what would the explanation be for this?

Thanks
RG

The trans field is blank and the engine number is all zeros on the PHS-provided billing card for my Framingham-built ‘68 GTO. Didn’t think these two fields were used anymore on the billing history by ‘68.

I know the Firebird in Lordstown had them. Possibly the non-full Pontiac plants did that? (combined chevy and Pontiac plants)

Well, checked a couple Pontiac and Fremont had them. Maybe just Baltimore and Arlington?

Default 68

I know 1968 was the first year for engine partial VIN stamps, therefore, the EUN wouldn't be needed??

Default Thanks for your response

Thanks to all for your response I am guessing that because the serial numbers were stamped on the engine block pad that they did not do them.

Thanks again

RG

My 68 GTO was born 11/22/67 in Pontiac Mich, and my paper work has the ID. numbers for my car.

My Fremont 68 didn't have the EUN or trans ID. Just blank spaces

What's the body date?


I checked about all I have and this is what I found:
Baltimore had EUN printed thru Oct 1967 after seemed to be zero's
Pontiac had them
Lordstown had them
Arlington had them
Fremont had them ; Some had partial EUN with leading engine code (except OG68 above)


Baltimore did not after Oct 67
Van Nuys did not
Kansas (K) did not
Canada did not
Framingham did not (didn't have many of these)

I guess there is always one in the bunch.



I have one on each side of that date with the EUN.

Probably around 64xxxx EUN.

HD 3 speed on the floor?

I have PHS documents for two Framingham built cars. One is a Feb. 1968 built '68 car that has all zeros for the engine unit number and blank for transmission unit. The other is an Oct. 1968 built '69 car. The engine unit number on the billing history matches the last four digits stamped on the block below the head plus the engine code (YS) and the transmission unit number is blank.
