sbrinz,
Have you ever done ANY upholstery work before?
I have had 2 sets of seats done by two different professional upholsterers that had never done 928 seats before. Both times I was told that neither would ever do any 928 seats ever again and please do not refer any 928 friends to them for seats.
Not to dissuade you, but that doesn't sound like the kind of job that a casual upholsterer would want to start with.
Rob Budd (
www.classic9leathershop.com)sells seat recover kits. (same ones he installs just without the installation)
I think Dean Fuller(on this forum) was thinking about recovering seats.
You might give these guys a shout for guidance.
Good Luck.
