The original Mopar strut bushings had a thicker and thinner
section (right photo). If this is not done the lower control arm is pushed back causing
it to slip on its pivot bushing if polurethane, and/or causing undue wear
and reducing caster in either rubber or poly.*
To obtain the thin rear section on a strut rod bushing, it appears
one could buy the "Moog Improved", or one can modify a standard polyurathane
(or rubber) A/E body set as shown below.
Note: there was also a one piece rubber bushing that originally
came on most if not all a-bodies. It wasn't much fun to remove, and apparently
was not used as the prefered replacement even by Mopar.

* A lower control arm being pushed off a nylon bushing from a too thick strut bushing can be seen at www.Firmfeel.com. They offer an adjustable strut rod as an alternative way to get the same results I did.
