Disco 1 seat upgrade

Hi all. Just been offered a set of leather seats out of a p38. Will they fit easily into a disco 1 xs model. The seats on my xs seam to have wider runners than the es model. Anyone tried this conversion. Also, whats the story with wiring the electrics????? Im looking for a little bit of comfort in my old age.

Can't help with the elctrics, but if you search there a few threads on fitting different seats. Easy job you just need a square of metal thick enouh to take your weight
