Time to fit the Mirrors but with 5" Mirror Heads, not as straight forward as you might think.
The 5" Head studs had less thread then the 4" ones so I needed to grind or removed the extra metal
So what I did was to get my 4" Angle Grinder with a nice new 1/4" thick grinding disc and mount it in my
vice, I then started turning the mirror stud untill it was at the same thickness as the thread until it fitted
So here you see the finished result, looks quite neat I think.
