Help with ID'ing truck-67 GMC

[Bagd72Chevy]

I picked up a 67 SWB GMC C-10 at Shades of the Past this weekend. Its a running/driving truck that I'm going to clean up a bit and drive around while I'm finishing my 72. The id sticker in the glove box is illegible unfortunately and I find this truck really interesting. Is there a way to decode the vin or any other way to figure out what this truck was from the factory?

It has:

Big Back Window
Leaf Springs (its a gmc)
307 V8
Th400 (The column shift says PRND21, so it was originally a 3 spd I assume)
Buddy Buckets
Looks like originally a white truck
Blue interior
Black dash pad
door panels are missing
Has the tall emblem on the front fender behind the wheel
No side trim
I think it has a 68 grille because it doesnt have GMC stamped in it????

Any ideas? I'll work on getting some pictures. My plan is just to clean it up fix a bit of the rot and enjoy the hell out of it.
