[TR] TR4A upper wishbone bushings

[Greg Lemon]

I put new upper rubber bushing in my TR4A  few years ago, they didn't last 
long, maybe I didn't get them on right (couldn't ask questions on email 
lists back then) anyway, I replaced them with poly bushings, which are 
pretty reasonable for a set, I thought the steering and general handling 
felt more precise with no deterioration of ride quality, and keep them lubed 
properly (silicone grease) and they should last a long time.  I know there 
are differing opinions on poly bushings, but I think for this particular 
application they work well, have them on my TR250 too.
