I am currently working on a Model B ampico restoration, and have 
a noise in the main pump.  The pump has been completely rebuilt and
cleaned original bearings.  I am pretty sure the problem is with the
bearings, however could also be the rubber grommets to mount pump.
My questions are 

1. Does anyone know the diameter of the bearings?  Are they the same
diameter as the model A bearings?  I have a Model A Ampico I'm working
on that I can measure and buy extra bearings for that.

2. Does anyone have a supplier for the rubber grommets holding the
pump, or a proven method of fabricating?

I would like to have all materials in hand when I pull the pump down as
I am still doing pressure test and regulations on player unit.
