I just looked up Cuda alternators on Ebay to get a look at the back of one and I see what you are saying about the two male connectors not being grounded to the case. I tried to attach a picture of mine and the file was to large but mine is defiantly different. I bought it at a local parts store about a year ago. I would have to say at this point they sold me the wrong one. It is defiantly hard to find a good local parts store that knows anything about old cars. At least this time (thanks to you)I will know what to look for and test before I leave the store.
