I got my 1977 280Z out for the first time this year and when I accelerated from a stop a steel bar in the rear suspension broke. I'm not sure what the bar is called, maybe a trailer bar or sway bar or mustache bar or strut support? It is bolted to the frame/unibody in the center right behind the rear axle and connects to each side under the struts I believe. Any ideas of what it's called, how to get it off, and replace it? Thanks! Jeff J.
