Looks nice
I noticed your passengerdoor mirror install.
Did mine last winter
saw there was a reinforcement bracket in a door I had laying around the shop.
So, I made one from a piece of sheet metal.
But thought those guy's at chevrolet know what they are doing.
Maybe I will get cracks in my fresh paintjob if there is starting some metalfatique
from the mirror/arm weight vibration on my hot cam.

So I got out the old bracket and reproduced one for some better stiffness.
just my 2 cents
keep up the good work
the truck is getting better and better
