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 !
