Gustav, 1963 VW Double Cab Truck

Stock side mirror parts came from Wolfsburg West.  I'd done a bit of research on theSamba forums on the best method to remove the upper door hinge pins.  The easiest method recommended soaking the pins for three days prior to doing the work, buying the right tool, and taking your time.  The tool I bought was a $25 hinge pin removal tool from Bob Drake Reproductions.  This tool worked as advertised!

 

With the lubricant applied I chose the right metal pin to install into the tool that fit over the upper door hinge. Then I used a 19mm socket to slowly tighten-down the screw, forcing the pin upwards. It took less than two minutes to get the right side pin out, easy! I kept the door closed to avoid the hinge dropping off, and quickly slid the new mirror arm into the hinge hole. With some WD-40 it slowly worked its way down. A 13mm socket was used to tighten the lower nut to keep the arm in-place. The left side was a bit different because the lower nut had rusted onto the bottom threads and was not able to be removed. So I used one of the metal pins with a hammer to pound the pin down out from the hole, easy! This side took less than a minute. 

 

The whole process took about an hour, taking my time and doing things right.  The new stock round side mirrors look fantastic.  Strange that they are at different heights, but that's the way it was done in 1963.
