VIN Question

[Tomahawk30]

I think I've already made my decision on this, but I want to make sure I'm not just being overly cautious. I'm looking at buying a 72 Cheyenne Super k10 swb from out of state. They had a local state police officer perform a vin inspection on the truck for me, which he approved. However, the id plate on the door frame is apparently not there, and he approved it based on matching the title to the SPID sticker in the glove box. My local DMV assures me that they would have no problem issuing an Oregon title for the vehicle based on his inspection, but for me this raises a huge red flag. Short of the owner (who is ten hours away) verifying that the partial vin on the frame matches up with the title and SPID, there's no way to know if anything outside of the glove box door matches up with the title. As truck owners / buyers, would this essentially discredit everything about the truck down the road? At the least I would think that I'd never be comfortable selling it to an out of state buyer as the next inspector may or may not be as accommodating in accepting the SPID as proof of the VIN for an out of state title transfer. I'm leaning strongly toward just walking away, but wanted to get a little reassurance that I'm correct in my assumptions here. Any input you all have would be greatly appreciated....
