Thanks Jeremy , that is promising , the donor car is a 2001 Aero so I may be in luck . At this stage I dont know how good or bad condition it is in , but it might be a better base to refurb.The Aero didn't get the Viggen's front bumper until 2001, from the looks of it. You can still get the front bumper from Saab, but it's pretty expensive, almost $1000 USD at the moment.
Make sure you get the black plastic mounts that attach the bumper to the fenders. They are different. Also get the under shields - they are also unique. You can run without the shileds but it's better with them. If you can get all the Viggen bits at a good price, I'd go for it.
