The answer is, the upper control arms do NOT have to be modified IF the chassis hasn’t collapsed. With time, some cars have experienced partial collapse of the chassis, due to the relatively weak support provided by the stock fixed-length camber bar. If an adjustable length camber bar is used, and the chassis is forced into its original position, then the stock upper A-arms work perfectly.
Adjustable or longer upper rear A-arms are normally a band-aid fix (which admittedly works reasonably well it seems....)

This question brings up a curiosity I've had about #6328 since I first
put
the adjustable Alden coilovers, then the set of Konis from DQ, on the
car.
I wanted to set the ride height such that the car was level all around
and
the rear lower A arms were parallel to the ground, what I understand
was
Dallara's intent when he designed the suspension for the Pantera for
optimal
handling. However, I could not quite get there: When I went to adjust
the
front coilovers, there is almost a 3/4" difference left to right to get
the
front of the car level side to side. When I realized the right front
was
the limiting factor, I adjusted the rest to match, and had to stop
there.
At this setting, when measured at the rocker front and back, both
sides,
there is no more then 1/8" difference at any location. This was done
with a
full tank of fuel, but without a driver. The car would still have to
drop
another 1/2" to get the rear A arms parallel to the ground.
Does this affect the way the car drives? Probably not, but it became a
curiosity when I was trying to set it up. I did not do any other
measurements to compare such as the distance between shock mounting
points
side to side, etc., and will have that checked and corrected if
possible
when the car goes in for restoration in a year or two. I also know the
car
was hit at some point in the left rear, but don't believe that twisted
the
monocoque as all doors and panels align properly and the majority of
the car
is dead straight (some sheet metal issues where the repair was done
that
will need reworking).
Thoughts? Is this not uncommon?
What say you?
Thanks
