Looks like you are reatively new here, welcome!
This forum is loaded with threads about swingarm maladies and fixes, try a few searches; the knowledge base is purely amazing.
You can replace the busings/pivot, you can utilize the clamp method of pinning your pivot so that there is no play or you can send your swingarm/engine cradle out for the ne plus ultra treatment at CNW and be done with it for the rest of your life. Unless the play is somethimng you can feel (while riding) I wouldn't worry too much about it, do keep an eye on it in any case. If you need a reality check go look at the swingarms on the crotch rockets, then look at the Norton's swingarm, very humblimg, to say the least.
Is everything else is passable shape? Pictures?
