So for anyone else that falls in this position you will need a 7-rib serpentine belt at no less than 53 inches no more than 53 3/4 routing the belt the same way just instead of going around the AC pully from the idler pulley go straight from the idler pulley to alternator pully and so on.

I used a Duralast 535kk7 and I still had a tension pully from when I replaced all pulleys a year ago and I used it in the place of the OEM idler pulley it is just a little smaller than the idler pulley and everything fit perfectly no problems at all. So hopefully this helps someone as much as it would have helped me.

Just completed this project. I used a 540K6 belt. It’d 6 rib not 7, but works fine. I also replaced the upper idler pulley with a factory tensioner pulley because it is a little smaller. You need a little extra clearance if the belt isn’t going around the ac. Hope this helps someone!
