I'm not too familiar w/ your gen X1 but is the part you're looking for P/N 51128083650?

#11 from this diagram (RealOEM).

Also, that piece looks to be piano black(?). Not a bane that I have had to deal with before but, unlike body color parts/panels, I assumed those type of parts came pre-finished and not in need of paint. Perhaps others here can comment on that.
