I need one and all i can find are ones for 175 on GM parts. Its just the plastic piece on the inside. The lid wont go on because of the broken piece on the hinge pin.

 

You could probably find someone on CList parting out a car & buy the part cheap or find a good one at the junkyard, just b patient

 

I 2nd trolling CL for parts. It can be a waiting game for the right part to show up though. As for junkyards, if you have a local picknpull keep an eye on their website since you can search their inventory on there. A maro or bird hits the yard you'll know the date it was put in the yard.
