You're using the stock diff cover. You don't have to post pic's on it. It doesn't apply to me. I'm using the Z1 cover with the extra hole in the side. I was told that I couldn't use that hole for return because the axle sensor is in the way. I found a way to use it with a banjo fitting. If you want. You can post your pic's in my thread of your install. To show how you did it with the stock cover.
