I have read some about people having corroded body grounds, I have some suspicion that mine are. Can someone tell me where these grounds are, and how do I locate them?

I have already replaced both of my battery/starter cables, however I have not been able to find these body grounds. Can someone help me find these so i can check them?

Thanks!

This is for the 90 legacy, but should be the same.
