One more thing I have mixed feelings on.
boxed lower control arms.
The strut sweep looks to me like it requires twist to occur in the lower
arm.
Has anyone ran boxed lowers a long time and seen any signs that the strut
and arm can handle the extra stiff lower arm long term?

Don't know about part numbers but gather settings changed between
factory
bias ply cars vs. later ones radial ones. The '79 AMX and later Spirit
GT
definitely handle better and with better feel than my '70 AMX even
though it
has better than factory alignment and camber specs done to complement
the
wheels/ tires and offset, wider rims and tires, all new bushes and
reinforced suspension arms.
Something that did change, obviously, is that factory '79 and later
AMX or
Spirit GT's are small body cars with arguably slightly better
front/rear
weight balance particularly with the six.
In addition, the factory GT or SAMX ( Spirit AMX ) have a factory rear
roll
bar and a much fatter front bar than my '70. Whatever the changes -
small or
large - they make a world of difference. Your personal experiences
may
vary.
There are changes that can improve upon the factory offering. Ride
height
about an inch lower and front/rear spring specs more in line with what
the
B.F. Goodrich Spirit AMX's used along with using poly supported stock
bars,
or better, a set from Larry Mitchell plus a set of KYB's or Koni's,
new
suspension bushes, new isolators for the rear spring leafs as well as
the
perches, a better steering box or the box built by a performance
house, etc.
really ties it all together. The ride height change really needs to
accompany the spring change to make a real noticeable difference.

Dan,
First of all, congrats on getting some wheel time in the HMX.
Second:

I have to disagree with Andrew Hay on this one. AMC didn't really
have any
money to "radial-tune" the suspension, as GM did. As I recall, most
of the
part #'s for the front end didn't change between 70-83.
As far as modified spec's, I'd think the ones from "Performance
American
Style" would be a good starting point:

P.S. If you like the much more surefooted handling of more modern
cars,
stiffer shocks, higher-rate coils and an additional leaf or two in the
back
would help the Spirit out a lot. Last night, on a whim, I watched
the
Hornet and Matador racing along in traffic in the James Bond flick
"Man with
the Golden Gun", and was frankly horrified by the utterly gargantuan
yaw and
roll. How did any of us survive?
