Yaesu G-450XL Antenna Rotator

There have been a few questions about obtaining parts for the Yaesu G-450 rotator lately.
The one time I did a repair to mine, I ordered parts from:

Vertex Standard U.S.A.
10900 Walker Street
Cypress, CA  90630
(714) 827-7600

I have scanned and uploaded a PDF copy of my manual, so that you might find the necessary part numbers:
