With the help of this thread, I tackled replacing the drivers door card this weekend. The existing card had a big hole knocked in it by the seat belt buckle. A hole-less replacement card was sourced from Autolusso for £40. I have to say it was easier than I expected it to be. The tan leather insert from the original was prised off and inserted on the new card using the existing fastners which all went back fine. The only tricky part was locating all the brackets on the new card back on to the mushroom shaped lugs, but that done, it all went back well, everything works, and it looks much better so I'm a happy bunny!
