Bought used cobra crank from seller, part was promised to be good, had part checked out at machine shop and found that part was not useable. Part was not damaged in shipping. It was worn out while in an engine. There was excessive wear to #1 rod journal due a spun bearing or something which was not mentioned during sale. We could not come to an agreement so the matter went to claims though Paypal. Paypal would not help at all. Siteing that it was a color or fitment type issue. Now seller is unwilling to give any refund or return my emails.
