Hello Tracker1,
Yes, The side turn signal light.
The 68-69 light is shorter and the 70-72 is longer.
The photo is to dark to see the grill light.

John Mahler was certainly "in the know" - to say the least - when he ordered that ZL1, if this is the same John Mahler who piloted the Owens-Corning L88:

Hello Tracker1,
The John W. Maher is the person who had the 1969 Orange ZL-1.
The photo of the co driver is John Mahler.
The spelling is different of the 2 names.

More than one recent source lists it as Mahler. The Penn Garage invoice is possibly a misspelling of his name.

Hello Tracker1,
I see your source of the the spelling the name in the magazine.
I see the name on the dealers invoice.
I think the magazine misspelled the last name from the writer of the story
The dealer invoice has the correct spelling.
Thank you,
Drew

Not sure why the tank sticker of the Orange ZL1 has the actual RPO ZL1 code listed. My understanding is it should be L88, as Judski's yellow car is - but I have to go find my pics of the Judski tank sticker to make sure

You are correct in that John's last name is Maher

When I transferred from the assembly plant into engineering, the guy I replaced (he was retiring) had worked for Duntov.

He said Duntov would fire that stuff up right in the Chevrolet Engineering building and then go "rump rump"-ing through the hallways and out to the test track at the Tech Center.

He also said you had to keep your eyes (and ears) open or you'd get run over.

Where is this car? Has it been located? It was also at the 1970 Press Event with the LT1 Corvette etc. IT is a 68 Body with Stingray emblems and no antenna with Head rest seats.
