Sal, haven't you been back over to "shelbyautos.com", since you bought your latest Cobra?
Your old car is just about to come off the line!
My engine builder/installer, Tom Lucas of FE Specialties, had good luck getting needed parts quickly from Shelby. I'll ask him for the phone number he calls, when I see him tomorrow.
I'm going to see him tomorrow because I will be picking up my car!
Also try Kris at CSXinfo.net, he can help!
Good luck Sal,
jdog
