Ok those will work. You just need to get the needle bearings that go with the bell.

And you will need to get a washer to hold the bell on.
You will also need to shim the motor up because there isn't enough room to slide it over for that small of a bell. You can stack up a few washers or something else. I have some that came with one of my os motors. But i am sure that you get the idea
Edit: Hey thanks Wade didn't realize I put the wrong like in there.
