I recently replaced the rear sway bar end links on my '79 RX7. The new parts are Prothane 19406BL. The top washer on the bottom bushing set rubs on the outside corner of the body channel on both sides of the car. I am wondering if the replacement parts are too short. Unfortunately, I do not have the original parts to verify dimensions. Would someone be able to tell me how long the bolts and how long the sleeves/spacers should be for the rear links? Thanks very much.
