I need a bolt and washer for the crankshaft pulley on my 3K. new crank...old worn bolt won't go back in. Do you know how many are the same? I can find one for a 4K that is 13471C from JPcarparts .com but I can't find any pictures to tell if it's the same thing. I'm assuming it has to be this big and heavy for some reason...or can I just find a bolt that fits?
