[TR] TR4A upper wishbone bushing choices

I have not tried the one piece poly, have used two piece poly and rubber.
Both work fine, swear I can feel a little sharper steering and control with
the poly.  Poly may squeak a little if you don't apply some silicone grease
every year or so.

Rubber wears out a little faster, but should still last year's on a limited
mileage collector car, but they are cheap and easy to replace.
