Perfect !!! Thank you !!!! Stay healthy through these crazy times !!!!!

Appreciate your quick response, I’m doing the pulley swap along with the 67mm throttle body, colder plugs, JLT intake and the SCT tune. I’ve been building Buick GN’s for decades and the Shelby GT500 is brand new to me. I love the car.

agreed with Goose. It is deff loose and should not be like that. First thing to always to is remove the bolt and check it out and reseat everything before buying new. Usually if the bearings are trash, you can feel the grittiness an not so much a smooth spin with wobble.
These usually have flares on the bolts and washer or spacer of some sort and just loosen up over time.

Can anyone give more info on the 15mm for 6 rib? I’m going to change out my original serpentine belt and need to tackle this next week. The SC belt is easy.

What Info do you need?
I would t bet on the SC belt being easy your first time either.

I’m not sure what I need to do in the area of the 15mm. I was looking last night but nothing stuck out to me like the tensioner area for the SC pulley. I know what needs to happen there but the area to real ease the serpentine belt, I’m confused. Any steps or more detailed info is greatly appreciated

You just detension like any other tensioner and remove the belt.
If you want to take it off, just remove the bolt.
feel free to look through this video. Don’t beat me up too bad though. First time doing this on this car and with one big solid tank made it pretty difficult for me.
