1967 Fremont GTO EUN typos

[tom406]

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.
