Goofy VIN or is it me?

[BigOrangeUgly]

I was trying to make sense of my VIN to verify the year of my truck so I could weigh in on the poll, but I couldn't match my VIN with the info on the VIN decoder page. It is supposedly a 68 GMC, and yes I have double and triple checked to make sure this is what the badge says. Unfortunately, the model # that is supposed to be in the glove box is gone.

Here is the VIN, anybody have a clue?

CE10D-PB735XX

Thanks
