Of course the crumbling yoke covers were common on all of the old sets, even B&Ws as well.

I used a Home Depot paint can cover suggested by another VKer. Look at this thread post #27 to see a before and after picture of the yoke:

The cover fit on the yoke nicely. I made three small holes to allow the rivets on the shield that mounts on the back of the cover to snap into the cover.

I did my initial powered testing on the bench with the yoke plugged in but no CRT connected. I made many quick powered checks with the HV loaded by a 40KV HV probe. Once all the voltages, currents, and waveforms looked right I put the chassis back into the cabinet laying it on its side to get at the bottom of the set.
