Mylespeed. Yes they have a parts department. Their website is https://saabklubben.se/. Click top right to get it in English.
You will have to join the club before you can buy from their parts department.
A word of advice, they want paid by bank transfer. This is expensive if you ask your UK bank to do transfers to Sweden. The BEST thing to do is open an account with Transferwise. It's very quick, and very cheap.
Website is Transferwise.com
I have bought stuff from the Saab Klubben. Very helpful.
