1967 Fremont GTO EUN typos

I had the pleasure of inspecting/appraising two very cool 1967 GTO’s this year. Both had longtime original owners and had remained intact and unabused their whole lives. I had PHS ordered for both hoping to provide concrete evidence of original engines since Pontiac didn’t really do VIN ID’s on blocks until 1968. I learned that Pontiac’s computer system allowed 6 characters for the 6 digit Engine Unit Number, and that Fremont moreso than other plants opted to put the two letter engine code in before the 6 digits, effectively losing the last two digits on the computer card printout. I’m guessing whoever read the digits wasn’t the most consistent, because BOTH of these well documented cars (both have original window stickers and POP) have typos preventing absolute authentication. Ugh.

Hi Tom,

Aside from your small issue on these two Fremont built ‘67 GTO docs, it seems both cars were not sold New in California based on the engine letter codes.

Sold new in Seattle and Puyallup, WA respectively.

Yep, that's how Fremont printed the engine serial #'s on the CBH. Obviously a typo on the blue car's CBH which the POP was generated from. The green car looks fine, just as it should for a Fremont car.

I remember the green car being for sale on Facebook a few years back by the son of the owner. Very low miles as I recall, but had lots of aftermarket stuff installed.

Tom, are you familiar with the blue '67 3-speed for sale in Gaston, OR?

Hi Grant, sorry I'm not familiar with the 3sp car in Oregon. Your comments on the green car are correct, but note that the last digit of the EUN is a 4 but listed on the POP as a 1. Since the CBH omits the last two numerals when the engine code is added, it doesn't offer any kind of argument about the accuracy of the POP.

The blue car in Oregon has been for sale on Facebook for several weeks. It's a pretty nice survivor overall, but the photos aren't the best. https://www.facebook.com/marketplace...66735667821094

I see what you mean now, I was only comparing the four numbers on CBH and engine. That is odd to see two cars back to back with mistakes like that. I can see that being an issue with some potential buyers having skepticism.
