Just look all over ebay, thats where I got mine. What year is your car? Mine doesn't have any framework, its all fiberglass so I have to use hood pins on all four corners, no hinges, but thats the way I like it...

Here's an ebay link to the company I got my hood from.

 

I use a cheap probe with a built in light. When toutched from + to - the light lights up. Remember the brightness.To check to see if your ground is good, hook the aligator clip to the + side of the battery and toutchthe crimped part of the ring terminalwhere the grounds connects to the body. If the light is dim then that is probly where the ground is failing. If so, clean and fix this point. If the light is as bright, then the ground is good. If there is no light, then there is no ground at all, clean and fix this point. Let us know.
