Blazer Identification Question

[longhorn70gmc]

Hello All!
I have a 73 Blazer that has K5/Blazer on the front fenders. The line between the K5 and the word blazer is yellow. The Build sticker in the engine bay on the driver’s side has some issues with it where it is hard to see some of the info. I have no other identifying badges on the truck. Inside I have a spot where an identifier should be in the front of the dash on the passenger side, it is gone. From what I am getting from books there are three possibilities for what badge should be installed in the dash.
1. Custom Sport Truck
2. Cheyenne Super
3. Cheyenne
I really don't think there are enough options on it to be a Super. I am thinking one of the other two would be the choice of what it is. My question is: How can I figure out what the Blazer is?
My goal is to get the correct badge for the dash. I have heard of just plain K5/Blazers before, but was hoping there is more to this. The Title for the truck doesn’t say anything either. I welcome some education on this. Thanks all,
Respectfully
