T700 Mirror broken

I'm sure you can get the replacement at a KW Stealership.

Call the Stealership and get the part# and Google it, You may find it less expensive elsewhere.

From what I can tell, the mirror looks the same as a T2000, but I would contact the Stealership to confirm that.

Unfortunately, the T700 was a stop gap created to fill in the line up before the successful all new T680 was introduced, so aftermarket parts and accessories are limited as manufacturers didn't want to invest in a truck model with a short lifespan.

 

I'm pretty sure that it is available as a separate part, but I can't promise you that it'll be kept in stock. I seem to recall having replaced a couple when Navajo ran a small number of them.
Might have to look a little further and wider than the dealership to find it, though. Chances are, if KW does have it, they'll try to push you into buying the whole mirror assembly so they can get it out of inventory.
