I ordered this specific to replace BOTH TRAP DOOR BEARING'S.... THINKING!...Since your there this deep in to the transmission REGARDLESS!... if one of the 2 only needed replacing. Why would you want 2 of the same size bearing and STILL!... have to go and order the other bearing from the 2 that it calls for nope it's 2 of the same size bearing for just the counter shaft . Since there different sizes I kinda thought it was both to do them both...🤨I guess I have a extra one
