cranck pulley differences

[Nanner]

I just put a 6 bolt in and i have a question about the crank pulley. I bought a new one right before my 7 bolt walked so i put that on the 6 bolt and have been using that for about 200 hundred miles or so. But i just found out that they have different part numbers and i was wondering if i should put the 6 bolt pulley on or can i leave the 7 bolt pulley on?What are the differences?

if it doesnt fit your pulley would prolly not spin straight and it might be knocking up against the timing cover. if u dont hear it knocking against it i wouldnt worry, but i dont know anything about 6bolts. if it works it works !
