How do you mount these?
 

Stupid question, but I'm not sure. I decided to go with the 73 mirrors instead of the 71-72 because of the holes already in my door.

I don't know if the 73 mirrors have mounting brackets like the 71-72's. I got these off Ebay for $35. Not a bad price. There is a hole on the passenger side one though in the base. There is only 1 hole where it looks like a bolt would go through to mount to the door.

Hey Brian, Just A Guessing, Could They Bolt From The Inside Of The Door Out :(

There is a mounting bracket on the truck door, then a set screw goes thru the hole to hold the mirror onto the bracket. Brian

well, you could try the one leg up approach... ;)

(couldnt resist)

64fleetside is correct.

I thought about that but I might pull my back out :) :)
