Tried to get a idler arm for a 73 Mach and it is proving to be some what difficult. You can easily buy new upper and lower bushing for rebuilding them. Has anyone done that? I rebuilt the suspension yesterday and had to put the original idler arm back in for now. The new part sold to me buy a local parts store was totally wrong. I called TRW and was informed that it is now obsolete. So has anyone rebuilt one and how is it? Thanks.
