Mark,

	How could we possibly explain to the unwashed all of the neat little
tidbits of information we exchange on this list? 
Thanks,

To clear all this up, the '62-5 cars all use a low-mount style of 
compressor bracket set, all pretty much similar if not same. It's the 
'66-7 bracketry that gets confusing.

In '66 there were two basic styles of bracketry sets, one for the 95-110 
engines and one (high-mount) for the 140. The 140 actually had a first 
design set and a second design set,  though not all the pieces were changed.

In '67 ALL cars used the high-mount style. However, the compressor 
pulley was changed to a two-groove pulley, and this altered the spacing  
of the compressor mounting. Hence the bracketry was again changed 
slightly to match. (NOTE: If you buy stock a high-mount bracket set, be 
careful to make sure ALL the parts match. Mismatched parts can give you 
grief with the compressor mounting and might even cause the belt to 
periodically come off. Check for belt groove misalignment with the crank 
pulley.) These changes were to allow the use of a smog pump on 
California cars. For those cars, a special bracket was welded to the 
high-mount bracket, and other brackets were also used. The smog pump 
then ran off the compressor instead of the crank, with an idler pulley 
included.

Consult your GM parts book for illustrations.

Hopefully this makes it as clear as mud. (G)
