ITA CRX radius rod bearings

I am in the process of installing these bearings from OPM and I have a couple questions for anyone that has installed them. Other than the two washers that come with each bearing, is there anything else that is installed with these bearings. Like any of the stock parts? I was just looking at the setup and it seems that with nothing else installed, there will be alot of front to back movement with the radius rod. Is this how they are supposed to be or am I doing something wrong?

I really suggest you call Blake or Tom at OPM and they will talk you through the installation. The object of those bearings is not to have any movement back and forth.
