Does anybody know how many bolts the GM produced w-126 A/C compressor 
has to loosen in order to get the belt on?  I have my power steering 
pump already loosened and it has 4 or 3 bolts (I forget) that hold it on 
and one "adjustment" bolt.  For some reason I cant seem to find the 
adjustment bolt on the A/C compressor.  Of course being low down in the 
bowels of an oily enging does not help especially in the dark.  I am 
packing up the tools now and will probably try again in the morning.

Absolutely! I have done way too many, lately. 3 19mm on the back side and a
10 mm adjusting nut from the top.

Additional information.

The top inner bolt uses a spring washer and no spacer - bolts right to the
compressor

The bottom bolt uses the thickest spacer between the mount and compressor.

The bolt that has the mounting for the hoses uses the slimmer spacer due to
the adjuster. 

I'll be doing another, this weekend. (A unit from a Chevette bolts on with
no changes, pulley, etc is the same - most Chevettes die early, compressors
are barely used)
