Hi,
the video gives a step by step tutorial how to replace the seatbacks on the Porsche 944, 968, 928 and the G-model of the 911. A common problem is the wear on the outer side of the drivers seat. The seatbacks are absolutely identical, thus it's possible to interchange the seatbacks of the seats. Doing this leads to homogeneous use of the seatbacks before you'll need a saddler.

The video has a German soundtrack, but English subtitles are available on YouTube. If you don't see them by default, watch the video directly on YouTube and press the subtitle button below the frame.
Enjoy it.
