Hi,
I finally fixed my frint windows,
There was the big arm with the gear.............this is made in 2 peced welded togetehr with 4 little point of welding...........aftre 6 years the welding point where borken and the 2 surface were sliding .....
So I did not get a goog MIG to weld and i preferred to drill , tap 4 holes with M4 tread and after i put 4 good screw.
the proble is solved and the arm is stronger that before.
Many thanks Guy
