Sounds like it has a salvaged title.
The only problem your going to have with a Honda of that vintage is finding OEM parts for it.
Its going to be like an Easter Egg Hunt finding stuff like the petcock, fork brace, etc.
I'd be more concerned with hidden damage on the bike, like steering bearings and if the fork legs are bent, this could be the reason your missing the cross brace.
Your probably going to need a new clutch slave cylinder, and rebuild all of the master cylinders.
This may turn into quite a project for you in the long run, but at least you'll learn how to work on your own bike, as most dealerships won't work on a bike older than 10 years old now.
Good luck.
