You are right Mother - I have found similar rods and the mirror - separate items on several big truck websites, but no mount kit even close to the one on the truck. It is good to know it was an original accessory part. I will look for the original GM mount you were able to share with us. I appreciate that help. Not sure where or if such a part may be found though, but I will start looking. Anyway, thanks for your response, and for the great pictures you included.

Todd, yes, the mirror is mounted on the rod as you described.
