A/C idler pulley availability?

The belt adjustable, A/C idler pulley on my '65 Galaxie, 352 engine, is starting to rumble and vibrate much than I want to tolerate.

Anyone have a source for purchasing a new replacement part?

Evilbay lists a couple of 'em for the 390 T-bird engines; but the chart availability doesn't list my Galaxie.
 
Those epay auto part "application" charts are often wrong.
That info comes from the seller and is only correct if they actually know all the applications for the part (not just guesses) and bothers to put them in.
Sometimes a seller will put down that the part fits a car/model that it actually won't, just to get more folks to look at the ad and buy it anyway.

It's better to know what other cars use the same part(s) for yourself and not rely on information from who-knows-where that is often incomplete, or just plain wrong.

Hopefully someone here will know if the 390 A/C idler pulley part is the same as the 352.
Since they're both an FE engine there's a good chance, but I don't know for sure.

Sometimes you can get the interchange info from a good parts-counter person.

Don't know about factory installed AC systems but for after market idler pulley the bearings are replaceable and I have used GM Alt bearings to replace it. There are 2 different bearings, one sealed and 1 just sealed on one side. Worth looking into.

+2....
 
The GM alternator bearing is used up to 2007, I have one in the idler in my F 150. I have used them in lawn mowers too.
 
I did email the ebay seller, asking if the 390 engine idler pulley would fit on my 352; no response yet.
 
No reply from the ebay seller.

I did receive an email from "Larry's T-bird" store. He believes that the FE 352 & FE 390 idler pulleys should be interchangeable. He emailed me pics of the FE 390 T-bird pulley. They look exactly alike to me.
