Searching for model type.

Having that AC control (the only picture you have posted) is not a 74 and the script is more from the 81 on up you may have what we call a Frankentruck since they can be built up using any of the 73-87 components.  Post some pictures but even after that 43 years alot of stuff could have been done by the previous owners

I figured as much as far as "Frankentruck" goes, I knew right off the bat some fishy stuff went on with this truck as soon as I saw the GMC logoed dash pad (my VIN points to Chevy). Looks like I will be removing those controls and replacing them with an aftermarket A/C system. Hey at least it's running great!

Ah screw it, I'm just gonna slap a Custom Deluxe 10 badge on it and call it done.

Mine is a frankentruck also

Or a snowball truck
Picks up a little bit from everywhere

Ours came with a Arizona state issued VIN riveted to the doorframe
With matching title saying 1980

All Numbers ground off of engine transmission and frame

The radiator support has a 1980 sticker for a straight six
The grill is not a 1980
The doors are the one year only 73 model with the tiny rollers on the regulator
The cab is a 76-77 with the separate shoulder belt spool

Has the GMC Sierra emblems on the front fenders with a Chevrolet Stepside tailgate  and bed

Had velour bench seat from a cadillac
  Hacked up Trans tunnel
And a couple of bullet holes in the cab which we have not repaired since they add character

Dang brother that is a Franketruck... but you know in the end it's about the enjoyment we get out of these old hunks of metal

 A long shot, does it have the original seat, maybe a build sheet inside, if they did that.
Your not going to get much from a resto package from GM.
Records weren’t kept and what was was lost to fire.
Generic info mostly

Yep
The truck actually belongs to my teenage son
   When he was about 14 he started making noise about wanting a car so  we told him we'd buy him a car up to $5000 if he learned and became fluent in either Spanish or an Asian language


Didn't hear anything for a few weeks so thought I was off the hook
   Then one day he says he says "I have my first Spanish lesson on Friday and I want a 68 chevelle "

No problem , probably gonna be a 307 with a power glide but we will start looking , has to be able to drive onto the trailer , and we need to not spend more then $3k on the car and save 2k for fix up

We found a couple but nothing that wasn't bad rusty and one Saturday morning we are playing video games and he says
"Who's that ? Is that uncle Chris ?!
Is that his truck ? !"

My brother had driven up in his 1980 black 4 speed  Stepside 4wd

He thought that was cooler than any chevelle

So we found this fine specimen in Arizona for $1600 and had an acquaintance who was coming cross country haul it to us
