I have everything that bolts to the Z axis carriage. The motor, controller, spindle, etc. I have all of the original pulleys and belts and motor mounts as well as (currently installed) a 4700 RPM conversion I made quite a while ago. I would assume that the 3 bolt pattern that bolts this to the Z axis is identical for G0704 so this would be an easy upgrade to a belt drive for G0704 owners.

Here is a video of the spindle at 4700 RPM...motor sags a bit but this is a big slotting cut with 6mm end mill.

Here is video of making the new pulley.

Everything works and is in good shape. I'm in the Dallas, Texas area if interested, or I can quote shipping if you want. Can also provide pictures.

If you want a backup, want one to play with, or you just want the 4700 rpm stuff, make me an offer.
