VIN Code Help

[claybobcustoms]

Hi guys I'm fairly new to the board and have really enjoyed the time I've spent lurking around here. I have got a 68 GMC that my dad and I restored about 12 years ago. I have gotten the urge to tear back into this truck and do it all again. I guess where I am going with this I remember the first time we had alot of trouble with parts because the counter guys at the parts stores had no idea that there was any difference at all between the Chevy and GMC or even the different year models. The worst part at that time was the fact we didnt have resources of the internet that are available to me today. So I am trying to learn as many different facts about these trucks as I can. Enough with my rambling... I decided to get my title out and decode the vin today and I am running into trouble. I'm not sure if there is a type o on the title or what the deal is because the truck is at my dad's house so I can't compare numbers right now. The title says the vehicle identification number is CE10DPB49044. I used the decoder on this site and a few digits don't seem to match up. Can anybody help???
