Gordon,
=A0=A0=A0 The only "bushing" that I am aware of in the front= iron hsg would be the
eccentric shaft bearing in the front stationary gear...............It = is replaceable
if worn out of tolerance............It must be pressed both out and in= and because
of a "tang" must be removed from one side and installed from= the other side
while making sure "tang" is aligned with the notch in the st= ationary gear bore
which also aligns the oil feed holes in both the bearing and gear.....= .......Job
requires a hydraulic press and a tool (either fabricated or purchased = from
a vender such as "Mazdatrix", "Atkins", etc) or fa= rmed out to a local "Mazda"
dealer or machine shop..............
