Greetings and Welcome! try Abbott Racing in Wix, Essex, tel: 01255 870636 and ask to speak too; Ed or Giles! tell them what you are looking for and that you were recommended to them by Dr Reid and they will look after you!
and EXPENSIVE hands. haha no I'm kidding nothing against Abbott they are amazing, they used to be the only Saab tuner around, therefore they have higher prices but amazing products.
Yes there is an ouch! involved with Abbotts prices, but they are at the higher end of the Saab performance market!
I have used some other companies who sell various tuning parts for your model, have dealt with all of these people, and they all deliver to anywhere in the world.
