I am currently working on replacing my sway bar rubber bushings on my 58. I ahve all the rubbers however the FSM says "the sway bar cushions are not serviced separately. If replacement is necessary, install new sway bar assembly". On removal of this I have found that there is a welded peice between the rubber bushing and were it clamps down the strut bar. Has anyone replaced these on a 58 or have you replaced the whole assembly as stated by the FSM.RegardsChris Wardle58 Imp Crown Coupe
