Does any one know when they changed fron the extruded aluminium section to the formed hardened metal for the BX window runners?...
My 1986 one is ali, and my 1992 is hardened metal.
So some where in between it changed...
The hardened metal ones rust away if not waxoiled or similar at intervals.
It is also quite difficult the make up a suitable profile, and it does not weld very well to the hardened metal..
I used some galvasnised sheet for the repair, one more still to do, Ho Humm !!!...
Any way, here is a picture of my repair to a rear side vindow of my Visa,
may be of some help.
Has any other member performed this task ?.
Cheers
