Idler Pulley Importance

The idler pulley is necessary to reduce the free belt length from alternator to PS pump and prevent belt flutter at higher rpm. You can leave yours as it is temporarily as long as you keep the revs down. If you rev the engine high, there's a risk the belt could get thrown off.
When you remove the AC just get a shorter belt and run it from the PS pump around the water pump pulley (CCW), then the crank pulley (CW), tensioner pulley (CCW), alternator pulley (CW), and idler pulley (CCW).
Just remember that as a general rule, the grooved pulleys spin clockwise and the smooth pulleys spin counter-clockwise so that should help you with the belt routing.

Yea, I have mine by-passed until I get one...

Mine is bypassed as well, and I spun 2 belts with it off, but I got the belt tighter by moving the alternator to the left with a homemade bracket till I get a pulley...someday.

Can I see a picture of your homemade alternator bracket?

I just use a piece of a tool box slide/lock bracket thing and drilled a hole for an extra nut and bolt and extended the belt slightly. If I recall, the parts store didn't have the right size belt. or something, so I didn't have to change the tensioner..
