Replaced failed strutrod poly-bushing today - Took video of working suspension

They were installed correctly, we may have had the conversation, I also feel. I have used both Delrin and Polyurethane as an engineer, not bad for the intended usage. Most of my stuff was "original", so maybe the parts were better or installed correctly from the factory? Anyway, you are correct in what you say, but at this time I still put the plastic bushings in the "not for my street car" category. I'm afraid you are probably right about available parts, even MOOG. I do have a stash of old heavy duty parts, since our parts are never easy to get.
