Im guessing the one in the photo is yours...and if so, it looks perfectly fine to me. You can slide it into the inner gear and check for fit prior to install...and if still concerened with it being worn Engnblr does have some of these. They arent included with the new oil pump by anyone. I got one from him last month when doing the final assembly and install of the new engine....which of course he built. lol Im sure he'll give you one hell of a deal on one.
