Hi Dave & Mark, I looked back into my research notes re the specs on these idler pulleys which were for 1959-1965 A/C RB engines which use 7/16² belts. The Mopar pulley accepts 7/16² belts and is 3 3/4² in diameter. The aftermarket replacement pulleys at parts stores accepted 3/8² belts. > I called Bouchillon. They say that their replacement IP is 3 7/8² which > probably would be OK. They also give a belt width range from 3/8-1/2² > > If the Bouchillon pulley works with no issues, then it seems like a good > alternative. At the time, I rejected it. > > Original bolt and pulley bracket have mating flats to prevent the bolt from > rotating. It is unfortunate that Mopar no longer has the bolt and shield > available. Hopefully those who use the Mopar replacement pulley have mounting > bolts and shields in good shape. > > Tony Rinaldi > > From: Mark Souder <MRS954@xxxxxxx> Date: Wed, 01 Sep 2010 19:59:54 -0400 To: <finsruskw@xxxxxxxxxxxxxxx>, Chrysler 300 Club <Chrysler300@xxxxxxxxxxxxxxx> Subject: Re: [Chrysler300] A/C idler pulley update Dave, Cancel that order and check www.bouchillonperformance.com and look for part number BPE4025. It is exactly what you're looking for, and it costs less than $24.00. You might have to wallow out the flat spot on your existing bracket, but it fits and works well. I did this on my 300H this Spring before I drove to Myrtle Beach.
