Lower control arm bush 1961Plymouth Valiant

There's been a few threads on here about issues with the currently avaliable lower control arm bushings. If I recall, there were some issues with the ID of the inserts on the bushings and the OD of the pivot shaft. As much as NOS sounds like a good ieda, depending how old they are the bushings might be dried out. There are also some options of other materials such as delrin that offer some advantages too.
