I'm definitely no expert on plastic(dirty word) but if it's rigid it's probably ABS,if softer and more pliable then probably polypropylene or polyethylene.
The rivets more than likely the former and the expander one of the latter.
I've got a '98 S-10 that I'm scrapping,I'll look and see if it has any of those things on it.
