Yes the threasholds on the 914 early style should be a clear rivet. The rocker panels are metal.
However, some of the 911s use these plastic rivets to secure a molding on the side also. So there is a crossover.
Also let me know if there was a mistake on your order and you wanted the plastic. I'll take care of you. I haven't listed these yet but will later this week.

My car has been apart a long time...and I am getting old(er)
BUT
I am pretty sure that the ROCKERS were affixed with metal rivets (and the rockers can be cleaned out\ to removing the screws/bolts, whatever you want to call them, that attach the rockers to the underbelly of the car. Most of the debris will fall out once those are detached, and a screwdriver or other implement can persuade the bulk of whatever else has been caught up, underneath/inside.
The thresholds were/are held in by plastic rivets...I believe more of a semi clear than a white, in the early years, and black later on.
