Ok... they did have the mirror with the mount. $60 shipped. (Much better than the $400 the dealership wanted to replace the whole side mirror assembly) I went ahead and ordered it from the hubcaps place.As for that other blue post... I'm gonna go back out to the highway and look for it.

With this info, is #5319RSG the backing and #5319 the glass? Can I order direct from these guys or do I have to go through some third party vendor?

Just clipped a barrel going through a construction zone and it popped the mirror out of the mirror assembly on the right side. Am I going to have to replace the whole side mirror housing and assembly?Have a look at the pics:
