Ok Im just wondering if anyones experienced this before. I got a 3.4 pully and the puller. I have the puller set up exactly the way the instructions are showing me, and the more I start turning the nut on the puller to take off the pully, the removal plate is digging into the stock pully. Now granted im not going to use the stock one anymore but im freaking out cause i think im doing it wrong. I know for a fact the puller was on there corectly, because my bro was helping me out and hes an ase certified mech. Needless to say i got the 3.4 on just fine and Im really pleased with the performance of my car now. If anyone can shed some light on this that would really help, thanks
