It's all so confusing, because I for sure have seen 1988 Monte Carlo SS's in person, yet they were identical to the '87, so then that makes you think they could have done it to the EC as well, and as far back as I can recall, even selling auto parts in '92 there was always a listing for '88 El Camino. How did that get started?
But... having said all of that, I, nor anyone else have ever seen one, so I don't think they exist. I think it's probable that they planned to complete assembly of some bodies for '88 (not re-VIN old ones) but they in the end decided not to. I'd imagine that's how all the auto parts store back in the day ended up with listings for '88s.
Just my two cents, which gets you very little these days! :yell:
