Ok, sorry if this is some where but search wasn't being very helpful. What I was wondering is if someone has the part number for an SI pilot bearing for the flywheel and a part number for the gsr pilot bearing. I'm just asking cuz I forgot to get one and if acura doesn't have on in stock I was goin to try an si pilot bearing so i don't have to wait over the weekend. So can someone give me the part numbers or tell me if they are interchangeable between an si and a gsr flywheel? Thanks
