So, I'm super disappointed to say I purchased a set of Poly bushings from Welsh in 2011 for the XK150 my Dad and I are restoring slowly.... They literally sat sealed in their packaging (in an airconditioned closet) until we tried to put them on a couple months ago and crumbled as we went to tighten them down.

Before anyone says "Well they are out of Warranty". Yes, you are correct. But I think we all expect Poly bushing to last under those conditions.

Can anyone recommend a good set they've used and would recommend?
