Ditto... the C-body longer idler arm is the correct matching arm for the "Fast ratio" longer pitman arm. MaMopar screwed up on the T/A and AAR cars (also carried over to some 71 model e-bodies) by not installing the proper longer idler arm with the optional "Fast ratio ps T/A box". Anytime a "fast ratio idler arm" is mentioned... anywhere... its truly just a C-Body idler arm. The FACT is... No one "developed" a fast ratio idler arm.. it was simply an oversight by MaMopar to not install it on those optioned vehicles.
