50th Anniversary Question

[jdodd68]

I bought a blue 68 c-10 a few month back. After looking at the glove box sticker and the help from all of you. I found that the truck was origanly a 50th Anniversary. I asked a few days ago what the origanl seats looked like in these truck but when i pulled up the seat cove it did not find that compination. At first I was thinking it was something someone put in later. Because they also but carpet over the origanl rubber mat and on some of the dash. Did they come with a different option than the one I seen before. Here is a picture of the seat.
