Did ALL 1977's get yellow painted side trim?

[Ellie Niner]

I'm looking at pictures of a yellow and cream colored 1977 GMC Sierra Grande, and the side trim inserts are painted the usual black instead of the honey mustard yellow unique to 1977. Queshun is: Did all 1977's start life with the yellow/gold trim? If not, what made the difference... body color? production plant? something else random?

Best of my knowledge, all 77s got the yellow trim.

But, I could see a really early or really late build getting the regular trim.

Another option would be if it was added or replaced with aftermarket parts.

Maybe someone else can chime in with more info.

I am curious, too !

The 1974 blazer I own had black paint on the trim pieces. My 1977 has gold (yellow) paint on the trim. The dealer told me at the time that it came in why it was yellow and he said they ALL had yellow paint on the trim. The reason he gave was BS. But regardless they were all yellow. Just FYI, for those of you interested in replacing the color on this yellow trim, IE restoration, the closest color I have found is called "NEW caterpillar yellow" at Tractor Supply.

What reason did he give?

What I was told, about why the '77s got the yellow trim paint stripes, is that it was in commemoration of GM's 50th anniversary.
However I can also see the possibility of a plant or assembly line running out of the correct trim and replacing it with the black stripe trim if that's what was currently available or on hand. I remember seeing new vehicles on the dealership lot with incorrect trim parts, back in the 70s when visiting them with my folks.
And then again, all these many years later, is a LOT of time for these trucks to get "incorrect" repairs or customization. Hell, my Dad was doing custom things to the '75 Sierra Classic right after he got it.... Headlight doors/bezels, door handles, cab headband, all got or were gonna get the black traded for Willoway Green. He was going to pull and paint the side trim when the truck got wrecked.... this logo delete on the cab headband was a mod I have never seen anyone else do on a square body truck. He used the Chevy corners as the emblem was smaller than the GMC and was easier to grind away....
Never did get to talk to the current owner about this truck, but it's got to at least have parts of his truck.....
