Replacing Defender heated rear window glass

On my M reg Defender H/T the heated rear window is almost defunct in
that only about two of the cross wires actually demist.
I see new glass are available so I was toying with the idea of
replacing it.
I have however no experience of such things so would appreciate all
advice from you more knowledgeable guys in the group please.
I saw a recent thread about the trials and tribulations of replacing a
front windscreen but hope the rear one might be easier.
It looks as if you undo endless little screws and it falls out- or is
that wishfull thinking.
But then would you replace the rubber type gasket on the outside.What
is that called/part no/sources please.
Are there any other bits and pieces you need to do the job.
Are there any tricks of the trade or traps for the unwary in the
taking out of old and putting in new.
Any more general or specific advice that I haven't even thought of
would be most welcome.Many thanks.
Finally any help with where to souce the glass and associated bits I
would also appreciate.(Can the glass be sent by post/courier?)
Very many thanks.

You can get silver conductive paint to mend the gaps - but if there
are a lot of them it can look pretty untidy afterwards.

A hell of a lot easier!

Not really. The miriad of little screws hold the aluminium strips in,
and the glass is bedded on sealant. With the retainers out of the way
it will push out - but be gentle and apply pressure as evenly as you can.

On vehicles up to 1A999999 there is no gasket as such (there is a glazing
strip from 2A622424) so the "rubber" you can see is the sealant.

Only some silicone sealant. If you have been careful the aluminiumn
strips are re-usuable.

Just remember that glass is flexible, and pushing to hard will crack
it.

I'll try that again.......

The glass may or may not have sealing strip (Part No. 78159)
on pre 2A000000 vehicles, and the part no. for the glass
is MWC4713.

More coffee required........
