Bridgeport M head bearings

[HMF]

There are a total of six bearings in an M head. A pair on the lower quill and another pair on the upper, all four of these are the same bearing. Then there is another pair in the drive pulley. Sorry I do not have the numbers handy.
The bearings are 205's and 206's

This is a diagram for the J Head:

Where's a good source for bearings; BP Series 1, Step Pulley, 1 hp?

I have found that this place is really helpful and reasonable. It is where I have been buying all my parts.
