A plain jane 7 rib serpentine idler pulley. I need two of them for my truck 5.7 project. The only ribbed idler on the Hemi is the tensioner pulley. The way I'm running the serpentine, I need two more ribbed idlers. It'd be really nice if the bolt was 8mm, too. Junkyard the best bet, just find something similar? I cant buy just the idler from Chrysler of course, I would have to buy the whole tensioner.
