is there a way to tell if the crank pully is the stock one for the sr? anything that can tell me if the pully is off of an sr or a ka? or do they just look the same? maybe size, diameter, timing notches?

 

if its aftermarket? or stock or whats it going on clairify a bit.. usually if its aftermarket i have seen for sr they are blue and anodized.. and the KA is silver/polished look but they do look different. I could help you more with more clear points.

 

If it's stock it will have rust. If you aren't sure if it is aftermarket then I would assume that it is stock as the aftermarket ones look pretty.
