Help 1969 GMC short Bed 4x4 4speed manual

[rayray767]

Going to look at a 69 GMC short bed 4x4 pickup tomorrow . Has a 350 O'Reillys crate motor with about 300 miles on it he says . Chevy front grill and Chevrolet tailgate . Bed,cab,floors,solid but will need rockers panels possibly cab corners if you want it done right he also says. What I would like to know is how desirable are these trucks. I don't know too much about the GMC side. I know they look cool and I'd like to have one but don't know a whole lot. I also know they don't come around very often for sale. I asked him the basics "is it a true short bed "yes" Gauges all work lights work blinkers windshield wipers etc. is good frame is solid. I saw pics it looks really clean. Do these trucks have the Vin tag on the door jam like the Blazers? Is the Vin number on the frame in the same location as the Blazers? Anything I should look at on the title to prove it is what it is? I'm thinking it should say short bed GMC 4 x 4
Is there anything else I should look for on this vehicle to prove it's a 69 and a short bed 4 x 4 ? Anyone know how many of these trucks were made? Which ones were more desirable the Chevy or the GMC? What do these trucks sell for all cleaned up? Any help would be much appreciated .
Thanks everyone 🤔
