Page 40.2 in Bentley's shows a torque of 54ft lb on the upper control arm nut
for the up to 10-84 non synchro. No mention of using different thickness
eccentric washers for clearance as per page 40.18 for the Synchro. Is there a
clearance spec for the non-Synchro control arm? I've got the same squeak and
my bushings appear to be OK.
