Plug in another vote for the C-Betr mirrors. As I have stated numerous times, they are worth their weight in gold.

 

I wouldn't waste my money unless the mirrors are installed on bodies that are less than 92 inches wide, they do however have small convex mirrors that present blind spots. I purchased mirrors from a company called Velvac who makes mirrors for these OE's and they are designed for specific models based on width, try them.

 

X2!

 

I bought these for my Excursion and loved them. When I sold the Ex and bought my new F-450, I removed them and will sell them now for 1/2 price- $20 (+ shipping). They are still in excellent condition and I highly recommend them.
