I have been reading about the aluminum trailing arms on '74 and newer cars and would like your opinion. Is it worth the effort and cost to do this upgrade? I am planing a big winter project including paint and some misc. mechanicals. The engine and transmission will be coming out for leak repairs and, in the case of the rear trailing arms, new bushings. I drive this car when ever it is not snowing or raining which, in Cleveland, gets me about 6000 miles a year. the car is rock solid. P.S. Thanks again for your advice on my recent seam welding question. I believe it was sound advice and resolved the issue for me.
