I ordered a tensioner pulley for my ZR-1. A 94'. But the part received doesn't seem to match the part on the car. The pulley received is Dayco part #89001. According to the information I was able to find, that's the correct part number. This pulley does have ridges like the existing pulley but it is about half to an inch to an inch wider in circumference than existing pulley. What am I missing here?
