bronco II mirror question

will the larger 2 point chrome mirrors work on doors that came with the crappy little black mirrors. I do know I would have to drill for the lower mount, but would the upper holes match up?

If you're going to drill for the lower bracket, you might as well drill for the upper ones.

true, but just wanted to make sure that the upper holes will not be exposed, once the upper bracket is on

upper holes will match up and the threads on the bolts for the larger mirrors are the same too. There is a brace that runs from the top mount to the second set of holes then to the bottom of the door to keep vibration down too.
