I have seen some f-150's with slide out/signal mirrors like the super duty's. the square one's come to mind. anyone know which ones fit?

 

I believe the '08 tow mirror is the one you've been seeing.

Also...

A few years back the Schafenacker mirror was almost popular. The base company behind it has gone through a restructure... and can be found here... Telescopic Trailer Tow Mirror by Visiocorp (I intentionally gave the pic link page to let you see).

This was the one I've been waiting on ... (funds permitting).

On Edit: the ones that bought out the Schafenacker mirror Corp. above...Iirc are the ones responsible for the newer Ford 2008 F150 tow mirror under the Visiocorp name.

 

I have a set of those on my truck. Mine don't have the turn signal on them, but they are available. I've been quite happy with mine.

 

do you have a pic?? cuz the ones i've seen look like the '09 super duty slide outs, squaeris looking, maybe the older ones would fit?

 

any mirror from any 2004-2009 F-150 will work

just pick a set from 04-09 and install them. the wiring changes slightly from year to year, but they all bolt up the same way
