Yeah, the index pin is in. The tensioner is sprung somehow. It's like it is coming apart. The back of the tensioner is flush with the bracket is bolts to.

I already tried the car-parts.com route and found out they don't index it. I sent them an e-mail to ask about it.

There is another site that send you quotes on parts and they index it, but all I've ever gotten from them is spam when they sold my e-mail address.

I'm hoping to get away and walk the chevy pick lot sometime tommorrow, I'll let you know what I find.
