Vent windows hinge

Where can I find vend window hinges? luckily I have a place here in town that will cut automotive glass fairly inexpensively. It's the these minor pieces that add up $$$$.

Here is a better picture of the hinge.

i hear ya. frankly, i could use a couple too. also, the plastic piece where the vent windows slides into on the bottom is broken on one side on mine. not sure what i am going to do about it yet.
