[Healeys] Off the Gauge & urethane bushes

[Bob Spidell]

Wow.  News to me, and makes me very concerned.  AFAIK, urethane bushes are in wide use--at least they're widely 
advertised, and presumably sold, including by trustworthy Healey vendors--and I've not heard of this issue before.  Some 
bushes are nylon--same problem?

Very worthy of discussion.   I would like to hear David Nock's take on this.
