You may want to call Greater Pittsburgh Collision Works. They're a body shop over near the airport and have done tech sessions in conjunction with the local PCA chapter. Another option would be to call Pete's Euro Techniques also near the airport, Pete is a great guy and freely shares info. Last, John Rayish (Porsche Specialties) in Bridgeville (412) 221-1855. They may be able to point you to someone local.
Different direction, try
www.car-part.com. It's an on-line system that the junkyard's use to inventory parts. It showed Flowers in Smithton, PA (about 20 miles from you) has a front right - I've been to that one, and front left is over in Malvern, OH about 75 miles - never been there.
Good luck. Looks like a substantial winter project. I'm busy with a house addition, but would be happy to offer some help.
