For a very long time, the stock idler bearing (extra light duty) was not available anywhere, and they failed frequently. So out of necessity, I found that if you're careful with the A/C compressor alignment on its mount bolts, you can eliminate the idler bearing altogether and simply use a slightly shorter vee belt with NO IDLER PULLEY! This is even easier if your car has the smaller, lighter and more efficient rotary compressor. Our '72 has not had an idler pulley in 40 years.

It's the front Idler pulley that's squealing. not sure I follow your comment... I don't have an idler pulley on the rear... The jackshaft drive pulley runs the alternator and a/c directly. Perhaps mine has already been bypassed as you mentioned.

This is the one that tightens the belt that drives the jackshaft on the front of the engine
