I thought it was spare tire delete. There was a past post when you had a car with x22 and some one mentioned x23 was spare tire delete.

73SC · A Poncho Legend!

When you search the web you can find X23 used for a few things depending on make. It does come up as Spare Tire delete for Chevrolet RPO's as well.

norontcan · Canadian Poncho Superstar!

Ray, I'm wondering why it would be necessary to identify a car as " fleet sales " as it was coming down the line? Unless it translates into things being omitted such as spare tire delete.

beaumontguru · Canadian Poncho Superstar!

Hmm, i think George Zapora is the only one that will know the real answer. You out there George?

I am certainly not interested in GM docs for a parts car sedan, plus i have the build sheet, just would love to know what that code is for all the Canadian car Gurus out there.

The car did have an original spare rim in the trunk along with a Gulf biasply from the 60's and the original jack.

Indian · Guru

No auto manufacturer used Gulf gas station tires for spate tires. As for option X23, hmmmm....na

4SPEED427 · A Poncho Legend!

I don't think he's implying the Gulf tire is an original, just a cool old tire from long ago.

Dave, way back when, Fred posted this list of GM RPO's. I'll post it up again as a refresher for anyone who's forgotten or has never seen it.

Cool, that must be it, the rest of the "x" codes in that list look like 1960's era codes.

Maybe the fleet code was used in the 80s or 90s?

At this point i am going with "spare tire delete". I guess you still got the jack and tools. Funny thing, the jack, base and cup are for sure originals, but i noticed the holddown rod and the wingnut were totally different from the usuall ones. that makes sense now!

4SPEED427 · A Poncho Legend!

Unless maybe someone did the wrecking yard thing later on because the car had nothing?
