Changing out the tensioner pulley on my 03 LB7. Bought a new one from my buddy at GM. The new one has a bigger bolt, and is plastic. The one on it which I am assuming is original, is steel and has a smaller center bolt. Anyone know if they swapped the part? Guessing I am in for a tensioner arm and the new pulley now?

Thanks.

It sounds like he gave you the wrong part. I got a replacement advanced auto parts, all steel. That was about three years back.
