Was there an answer to this that I missed?

Subject: REFLECTOR: Adjustable Seat Back Hinges
 
I recently bought the new adjustable seat back hinges from Velocity, but
have had difficulty getting them installed in a way that makes them
operate smoothly or freely.  Understanding that they are designed not to
mount directly against the seat bottom and back pans (but instead with
the seat fabric and a little bit of foam trapped in between), we have
tried using shims to simulate the thickness of the fabric and foam.  But
even so, we have still been unable to install them so that they operate
smoothly and freely or to allow the front seat backs to be easily folded
down nearly on top of the seat bottoms for easy ingress to the rear
seats and for the easy storage of bags behind the rear seats.
 
The basic problem seem to be the fact that the lower part of the seat
backs, where the hinges attach to the embedded hardpoints, are not
parallel which angles the two hinge axes and prevents them from being
co-linear, as shown in the photo below:
 

 
The angling also causes the seat tilt rod to bend and not operate
smoothly.  The adjustable seat hinges seem like a good idea, but we have
been unable to install them properly.
 
The question is whether or not someone on the Reflector has been able to
successfully shim the hinges to allow the seat back to move smoothly and
easily through it's full range of tilt forward motion, and if so, how
they did it.
 
Any ideas or suggestions from people who have made them work would be
appreciated,
 
Thanks,
Bob Jackson
