My coupe has a front anti-sway bar that is 28.67mm diameter-about 1 1/8". The PO put it in the car over 14 years ago in Hawaii. The red urethane in the rear sway bars look the same. The red urethane bushing is 1 1/32" ID and 1 7/16" OD. Both bushings and the red urethane end links are now pink and dry and powdery. I bought new red urethane end links. The restoration shop told me to look for rubber bushings since they have seen urethane dry up and crumble in our South Fla. weather. Does anyone know where to buy rubber and/or urethane bushings to fit this big sway bar?
