> But the way when I go to replace the screw will anything fall to the bottom of the door?
No. AFAIK, all doors have the nuts welded to the inside, it's just most don't have the passenger side holes drilled yet.
> Do i have to take the door panel off or can I just change out the screws one at a time with out any issues?
Right, just one at a time. It's super easy.
> Did you alter the finish on the mirror base ? I thought they were chrome like the mirror housing?
Right - that mirror is weird. All I've seen are chrome everywhere, as is my driver side. This was a NOS mirror I ordered a couple years ago and it just came like this. It bothered me at least, now I just think it's "unique".
> Did you drill out to hit those thread locations or were the holes already there?
I drilled the top door skin several years ago, but like I said above, I'm pretty sure all doors have the nuts welded on the inside, it's just a matter of finding the right spot on top (drill a very small pilot hole from the inside, or measure VERY carefully.
).
