Thanks for the pics...look forward to hearing about the mirror and seeing those pictures.
I found the whole mirror assembly on http://fordpartsdiscountoutlet.com/ford/focus-parts/
for $150/side. The mirrors are located under Front Door/Outside mirrors/mirror assy.
The parts diagram has the cover as separate part and is orderable as a separate part too; so I'm hoping that swapping the covers from my current mirror to this new one will not be too bad.
