I have an ex USA car 73 MT/E which had all the brightwork blacked out and resprayed from silver to a bone colour (god knows why!!!)
Its a very original car so I am returning the brightwork to shiny and will paint the car again sometime in the future.
In the process I had removed an powerd coated, black but otherwsie perfect, original 72/73 small rectangular mirror and was trying to figure out how to dismantle it so I could get the top stainless part re polished and the bottom re chromed to get rid of the black look.
It consists of 4 main parts.......base, mid section, (pic 2) stainless top and the mirror in its plastic surround (pic 3)
After removing from the car I tried to undo the nut under the base to seperate the base from the mid section only to have the thread break off...no big deal I thougt looks like its screwed into the mid section anyway so can replace.
Next I tried to remove the plastic half sphere from off what was left of the broken thread but wouldn't budge it was hard as a rock after 40 years but eventually managed to get it to twist off. Its there as part of the
mechanism that allows the mid section to swivel on the base.
Next problem was how to get the glass out...this is where I really went wrong.
I assumed that it was similar to the durant set up and was trying to prise up the outer edges of the plastic not knowing it was a whole plastic piece that pushes into the top section.
What I also didn't know until it was too late was that you need to get completely under the whole plastci piece to lift it up and you can only do that at the corner where the mid section attaches to the top section
as the plastic surround is cut away (pic 1 it faces down in the top section but I have it up so you can see cutout) at that area allowing a sharp object to be inserted to prize it up
Sadly i finished up with a torn plastic glass holder, a broken mirror (its thick glass too) a broken thread and one totally stuffed mirror now I suspect.
I write this so that anyone else trying what I did may have better luck than me
If you think I can salvage let me know how.
