I am putting together some arms at the moment to replace on a car. I have sourced the ball joints from the Saab 900 2.0L L4 Turbocharged. Moog part # SABJ0556. The inner urethane bushings are very close to the Shelby parts with a thinner head on the bushings. Do any of you AC gurus know the source for this part for the car that has almost as many donors as the 60's version

Thanks Nick
