Im fairly certain mine are these ones, for up to 2in tires.

work fine and are very well made.
a little finicky for installation with having to cut the stays to a given length in order to install the mount thingees (thingees are closed ended, not open, so one has to measure and cut the stays for your situation, for the end of the stay to seat into the thingees. Very technical term I know, but there you go.
Aluminum fenders mount faster than plastic and are all around better, but the plastic go better with my MTB turned townie.
