2001 sunroof part question - "stopper"?

[Clifford]

A small part on my sunroof broke and it prevents it from sealing fully. I think it may be Toyota Part No.: 63239-35010 "sliding roof panel stopper" but I am not sure. I need help identifying it so I can replace it. Below are pics of the remaining one (passenger side) and broken one (driver side). Also need to know what to lube the tracks with they need a cleaning.
Thanks
