Upholstery advice

[Baby Cheeses]

Hi
Just found a 35i GT Passat in a local scrapyard thats the same as mine, Knackered drivers seat. Has anyone swapped the backrest from the passenger on to the drivers side? I also need to remove the foam padding and material from the passenger seat base to fit on to mine, well at least some of the material. Any advice will be appreciated.
The car in the breakers yard is almost complete until I got there and its not the only 35i there the other being a saloon
