Help needed with door seal.

I have a 20 year old Leibherr fridge freezer. I am told that the seals are not designed to be replaced and that it would need a new door which is no longer available. I have tried fitting a universal seal but failed miserably, made all the more difficult by the fact that the bottom edge of the inner panel has broken off leaving nothing for the seal to push on to.

So I have been looking for a replacement fridge freezer. It has to be 75cm wide to fit into a space between kitchen units, and stainless steel. I cannot find one anywhere. Leibherr and Bosch advertise 75cm wide units but no longer make them.

I have two questions. Is there anyone who can make/supply/fit new door seals for me in the Bournemouth area?

Is there a 75cm wide fridge freezer that I have missed?

Please help, I have an ice mountain!
