Re-asking this question as I am in the same position and Exmoor have confirmed that they do not do Disco seats any more. Too much trendy Defender demand I suspect and people with deep pockets.
There are two small tears in my drivers beige leather seat squab that are beyond repair. So I have a number of options:
1. I can put some canvas underneath the affected area and secure it with Copydex. This will stabilise the damage, prevent it getting worse and the Copydex will not damage the leather. I can leave it like this almost indefinitely.
2. I can get a professional seat trimmer to replace the panel. Downside is that matching the leather does not appear straightforward and it would probably need to be separately re-coloured. Looking at £150 + VAT for the panel and about the same again to re-colour.
3. I can find the squab from a passenger seat (should be in acceptable condition and suitably patinated) and do a straight swap as they do not appear handed. This would be the easiest and probably best option IF I can find a suitable donor. Problem is that the drivers squab is the bit that is worn on every D2 and I'm unlikely to find a replacement on its own.
3. I can find a full interior, use the squab and bin the rest (I doubt I would find a buyer for an interior without a pax seat.) About the same price as getting a trimmer and new leather, but I have no where to store the remaining interior, so it would likely go straight to the tip, and that does not sit well.
4. With minor narrowing it would be possible to have the seat squab repaired using leather from a seat back, and there is one available now without the squab. But the seat would not be the same and I would know the difference.
My plan is to do 1 while I wait for 3, but it could be a very long wait. Does anyone know of a good beige leather D2 seat squab available?
