I am about to start the body work on my doors for my C-30 with a flatbed, stake rack set-up. I have never driven this truck, and am not sure how big my mirrors should be. Are the stock mirrors that bolt to the door with a single stalk big enough? The truck doesn't have any mirrors right now, only the three threaded holes towards the top of the door below the window. The reason I sort of need to know now is that it will make a difference on what holes to weld up, and what to keep. Any suggestions on mirrors that you guys are using, and where you got them?? Thanks!
