The poly bushings have a lip and are that thickness bigger than the
rubber bushings (that have no lip).  The lip on the bushing is the same
size as the lip on the washer that fits into the hole in the sway bar so
I'm wondering if I can leave the metal washers out on both sides of the
sway bar and just use the two poly bushings since they fit into the hole
of the sway bar just like the metal washers and the sleeve (distance
piece) fits inside them.

Has anyone else had to make a similiar decision with poly bushings?  Has
anyone left out the metal washers and just used the bushings next to the
sway bar?  Any theories, suggestions, cautions?  Guess I can just try it
and see how it works

Thanks in advance

No experience but here's a theory:

Since the poly bushings have a higher durometer reading than the rubber
ones (that means they are stiffer and harder) they can mold in features
that wouldn't hold up survive in a rubber bushing.  This indexing lip for
example.  If this were included in the rubber bushing it would be to thin
and the rubber would soon cut or wear away.  Molding this feature into the
poly bushing eases assembly and reduces parts count. 

Since the material behaves differently a different aproach is required for
the same application.  Just like the suspension bushings.  Rubber bushings
require much more pre-load compression than do the poly and concequently
the poly bushings are easier to install.

But, this is just a theory.
