Previous owner had quite a lot of aluminum in the air; enough stiff

sit precisely flat (gap is only a few .00" or so, mostly on one side)
causing the new mast to bind in the shaft between the top and second
plates partway around its rotation. Looking for suggestions as to how
to carefully force things back into reasonable alignment...anything to
avoid cutting off and replacing the top plate. Tower is on the ground
and easy to work on.

John,
I am not sure if what I am picturing from your description is correct.
The HDX-555 appears to have a top bearing plate with a 2nd plate about
6" below that and a short mast tube that is welded between these two
plates. If you can post a link to a good close-up photo, that would be a
big help (it needs to be a link since TowerTalk doesn't forward
attachments). If you don't have a way to do that, send me a picture
privately, and I'll post a dropbox link. Alternatively, you could post a
close-up picture to your QRZ.com page.
