i did search it but cant really find a specific answer-
i want to take out the a/c compressor in my 4.2 because i dont have a/c and the compressor is useless ( i am not interested in the OBA system yet so i will keep the compressor untill i have time and money to go that route)
so does anyone know the part number or anything for the pulley ide need?

I removed my AC and could not find an idler to go in its place... I simply installed a shorter belt which crosses directly under the thermostat housing from the power steering pulley to the alternator pulley. The belt is a Dayco 5060755, it is a 75.5" belt. I tried a 75 which was way too tight and a 76 which was way to loose in the process. It is just short enough to pull tension with the alternator. I have had no problems at all with this setup but if you wanted to order a custom length belt, 75.25" would be perfect.
Nope... There is about a quarter to a half inch clearance, so it is tight, but it does clear. If there is ever a problem, I will resume the hunt for an AC delete pulley, or fab my own. But its working great so far.
The compressor does exactly what that replacement bracket does. The compressor doesn't run unless you get 12 volts to the clutch. Unless you are wanting to sell the thing I would leave it on there.
If the pulley bearing on the compressor pulley is in good shape, you are correct. But the pulley bearing usually goes out before the compressor, and they are noisy as all get out as they slowly fail over a 6 month period.
