I need to replace the front crankshaft oil seal for my car. I received the part but it doesn't fit my 2004 v6 Mustang and I checked many times before ordering. But I don't know why it's a whole different part. If you see the photo above, then I ordered the top one and the bottom one was originally installed on my car. These are completely different parts. Please help me find the right part for my car. Thanks!
