I bought a second pair of aero mirrors.  These were produced for the 964 and 993 cars but fit perfectly on the 1974 to 1989 cars.  I have comnpletely dissmanteld them and stripped them of their old blue paint and repainted them in Porsche A1 black.  I have also wet and dried them as well as polished with a G10 compound.

Here's the mirror hopusings and bases:




and here's everything that needs to be re-assembled after painting:



In the middle of the pic you'll see a bolt and a number of washers.  This is a tool I made up in order to remove the base from the mirror housing.  There is a very powerful spring that holds the two pieces together and requires alot of force to compress them before you can take them apart.

Hi
If any one has problem removing the spring bolt asm i made up a tool. its a bolt fitted to a t bar you can turn the asm upside down put all your weight on it push down and twist without damaging the lugs worked a treat so if you want it pay the post and its yours
