One Year Only Stuff 73-87...
It seems like GM made styling and mechanical changes every 2-3 model years,
but what are some interesting one-year-only options and parts in the 73-87 (91)'s? This is just to make an interesting discussion...

Re: One Year Only Stuff 73-87...
Excellent question, and not one that I've seen posted before.
The most obvious item I can think of is the golden/yellow center side trim used only in 1977. Also trim related is the combo turn signal & headlight surround used only in 1979. The 1980 model had something similar (and maybe was identical for the round-headlight lower trim models), and of course the square headlight plus turn signal surround was unique to 1980. In the back of my mind I have a sneaking suspicion there were other one year only specific mechanical items, but it's just not coming to me now. And lets not forget a one-year-only ommission - the inaugural 1973 models were missing drip rails over the doors, which every year thereafter included.

Re: One Year Only Stuff 73-87...
1977 was an odd year. I am pretty sure the seat belts are 77 only, the door panel inserts on Cheyennes and Silverado's was a one year only trim piece. The dash insert is a one year only wood pattern for 77 also. Blue painted engines also started in 77.

Re: One Year Only Stuff 73-87...
Yep, my dad has one. He says if he can find another one that's clean with low mileage, he's gonna buy it instead of buying a new one. He's 73 years old and new trucks are just too big now. He still gets out and gives his a real hand wash and he just couldn't do a new one justice. "Can't even reach the windshield or halfway across the hood without getting on a step-ladder and I'm not falling off a step-ladder trying to wash a truck!" That's his quote every time anyone asks him why he hasn't bought a NEW truck. GTT

when i thought my 88 was 85 "To answer your earlier question: no TBIs on fullsize trucks in '85. We've had this discussion before and I can answer with confidence, because I 've had conversation with the GM Powertrain guys who did the calibrations for these TBI engines. They have said no TBIs until 1987 model year."

Speaking of, the GJ was the only truck to have the kick panel speakers from the factory. They also had unique bed rails, and the truck itself was a one year only. Same is true for the Beau James.

Re: One Year Only Stuff 73-87...
How about door panel speakers on the 1980 models?
And 80 had the combination of newer style gauges in the older instrument bezel and dash pad.

Re: One Year Only Stuff 73-87...
I think the 73 is the only year without a driver side tank option and the 74 is the only year with a mechanical dual tank switcher valve.

Re: One Year Only Stuff 73-87...
1975 was the last year with the engine displacement badge in the grille and the first year of clear front turn signal lenses and first updated grille.

Re: One Year Only Stuff 73-87...
My father had a 1979 K10 long bed that he bought new. I remember as a child seeing the number 400 in the lower part of the grille. He might have put it on there though.

Re: One Year Only Stuff 73-87...
It must have been added on from an earlier truck. I always thought the engine badge in the grille was cool, I don't know why GM stopped it so early on. I have a mint 78 GMC grille up on my garage wall and I put a 350 badge off a 1973 Cheyenne in the lower corner and it looks like it belongs there.

Re: One Year Only Stuff 73-87...
What year did they start the 400 engine?
I have seen 400 grill emblems and thought they started in '76 or 77? Quote:

Re: One Year Only Stuff 73-87...
Hello everyone, I believe 1981 was the first and last year to have the newly designed, squarish center console with the bucket seats. I do not see the bucket seat option in pick ups after 1981 in any of my literature.

Re: One Year Only Stuff 73-87...
1981 Cheyenne models are very rare. It's the first year for the new front end, but the Cheyenne trim package was still offered that year. If you can find the emblems for one, they're worth a pile of money. I found the dash emblem for one, and I bought it immediately for that reason.
