Edit: Should probably ask vendor first before posting here.

 

I'd personally return it for the sake of failure, and not taking responsibility of something malfunctioning in the future. Doesn't matter the defect or car part, because if it isn't perfect, it isn't going to work the way it's supposed to. Ask for a replacement due to poor condition when received.

If they refuse to replace it, go for Helix They've got quality parts.
Also, just reschedule your appointment. Inform em' that you had to return the part due to either a shipping or manufacturing fault and they're sending a replacement.

 

Such a bummer. My mechanic isn't available next until mid-September.

In the mean time, my pulley tensioner needs to be replaced. I bought the pulley upgrade since I might as well upgrade at the same time. Guess not...

 

Sorry, looks like you removed the pics. What is the issue?

 

His 15% pulley was badly damaged and was asking if he should return it.
