I have a set of Cipa Slip on Towing Mirrors that I used twice on my 2007 Ford F150 XLT Lariat. I am only selling them because I no longer own the truck, I went to a Ford F250. Mirrors are in excellent/new condition in original packaging and work really well. See the link for more information but they are really easy to use/install/de-install:
Amazon.com: CIPA 11800 Ford F-150 Custom Towing Mirror - Pair: Automotive
These retail for $50 at one site and almost $80 at another site so how about $40 shipped in Continental US.
PM me if you are interested. Excellent deal for anyone needing a good set of mirrors.
Thanks,
Scott
