(ET) deck motor armature needed

[tbamc <tbamc gbta net>]

I've found at least part of my 12M deck vibration problem:   One 
armature is slightly bent.  Doesn't vary the blade tip by more than 
1/8-3/16" but when I disconnect that motor, noise and vibration are 
significantly less.  Upper bearing 'sticks' in a couple of places.  
Could that be causing the problem, rather than, or in addition to, the 
shaft?
I'm going to start searching for a machine shop that's willing to try 
and straighten this, and another I have that's even worse.  Not 
optimistic about how successful I'll be, out in here in the middle of 
nowhere, so in the meantime if anyone has a tall, thin armature they'd 
like to sell, please let me know.  Or,  if you've got access to the 
equipment to do this, and want to give it a shot, I'd be happy to pay 
you to try it!
Thanks.
