Will a 530 o ring chain fit my CB77 without issues?

No. It's too wide.

Tim, thanks for the quick response! On another subject, is there an aftermarket seal beam that will fit the same? Gary

This is the only one I know of.

However, you should shop around on Ebay and similar for a headlamp assembly that takes replaceable bulbs. They were installed in European bikes. This parts book contains it. Searching by part number is useful as the vendors most often use them.
