I would definitely agree with that statement now that you mention it. it really does appear that the crank would take a flatter profiled belt than the cam pulley. These are the stock pulleys I can confirm with 100% certainty, so would Mitsubishi screw something like that up? I'll go get another belt today, put it on there, and take some pictures. Both belts that went were round profiled ones, but the first one was not the original OEM belt. The PO had changed them out before, so I'll cross ref. some part numbers until I can find a flatter one hopefully.
