Rust is starting to take hold in the channel at the bottom so i fear it has to come out

The outer stainless trim came off easy, i haven't taken the inside trim off yet- i'm hoping that the cage touchin the upper piece won't be a problem

The rubber is glued to the glass, the rubber is intact but very hard- would warming it 1st help?
Do i take the glass out of the rubber or the glas and rubber out of the car?
I've found a couple of bits in old posts- Will Datsun using lots of welding rods to hold the rubber back, Blue says to do it in warm weather which shouldn't be a problem at the mo, Bratfink warned against placing it on cold concrete (bet you love being reminded...

Alistair would you still have that wire rope?
6 of the clips have rotted away, anyone got a few spares? Will you got any plastic ones knocking around or are they easily available?
