D6H Hard nose loose

I'm looking at a 6H to buy and the hard nose moves back and forth when you lift and lower the blade. now I did research the replacement pins and in doing so discovered there is also bearings in the bors. So i'm wondering what my chances are that i could get away with just replacing the wear parts or if i would have to do some line boring.

The other issue is the hard bar. I know for sure that the end bearings are out but not sure if its eat into the bar its self. Not sure where to look...
