 He suggested investigating this, and possibly installing some shims
 somewhere between the mounting nut and the cupped washer which is just below
 the upper spring retainer.  And then just double check the torques
 everywhere.  But they admit that it is
 possible (but not likely) that I have some off-spec bushings.

    I would seriously doubt that a slightly off-spec bushing, that still fit 
tightly?, would cause a clunking sound.  I have heard a clunking as they 
suggest, however, with loose struts that are intended for a spacer to be 
installed.  Also, I believe that the procedure that requires bushings to be 
torqued with the weight of the vehicle only pertains to the stock rubber 
vulcanized bushings.  Delrin bushings have essentially no compliance to twist 
with the suspension, thus, they pivot on a metal sleeve that goes through 
them axially.  You will find this if you disconnect the ball joint, and 
notice that the control arm swings up and down freely.  I would check 
elsewhere in you suspension repairs for unnatural play.  Are you positive 
that the clunking comes from the a-arm area?  If it is, then it only seems 
right that Blau sends you a new set to be installed to see if it cures the 
problem...
