I have to apologize to Jeff and the many others who email me for taking my sweet time to post these pictures. The truth was that I lent these items to a friend and had to track them back down. The object is to compress the spring so that you can turn the support shaft to engage the upper housinig. Sounds alot easier than it is. However, get yourself a chunk of 1" copper plumbing pipe and cut 3/8" off of it. Match up a washer that will fit the tubing.

Go to Home Depot or Lowe's and by an offset clamp.

I have not shown the mirror body to show you how the copper/washer sit on top. The tool is to allow the spring to rise above the mirror body, and yet allowing the clamp to put pressure on the mirror without damaging it.

Once you have compressed the spring, you will have to use a drift punch to rotate the shaft (from the bottom) so that it engages in the locks.

Note: I used electrical tape to hold the washer and copper together, and for the picture I removed the spring and washers on the shaft for clarity.

Kevin, I may never have the desire or talent to take my mirrors apart but I really admire your ability to fathom out what is needed and then construct a tool to help achieve it!

Ruairidh;

Thanks for the compliment! It was like a brain teaser to come up with normal garage tools to get it to work out. I just hope that this helps someone, now or in the future.

I recently upgraded from flag to areo style mirrors and this post helped me considerably. The offset clamp is necessary to assemble the new mirrors, there's no way one is going to compress the spring in the mirror unless they have this clamp. No, there's no porsche part number with the request 500% markup on the price,, but simply go to your local Ace Hardware store and ask for a #1434 offset clamp by Adjustable Clamp Co. ($9 if I remember right)
This shows the original poster with the clamp.
In addition, I cut off a 3/8" carriage bolt and ground down the end to a point. The hex head of the bolt fits perfectly with the core of the mirror shaft, and it makes it easier to turn the core to engage the lugs in the mirror housing.

and this shows the clamp in action
