[T3] Horn Issue

[Jim Adney]

That's interesting. There's nothing wrong with having a metal bushing in 
there. It's important to have something that keeps the bolts from completely 
crushing the rubber. I assume those special washers meet in the middle to 
limit the crush.

I believe the OG part had canvas molded into the middle of the rubber part, 
to give it the extra strength it needs. Does this one also have the imbedded 
fabric? I'd be reluctant to use it if it didn't.
