Mate i have trouble posting pics, video
The YZ's in the musem so i wont be riding it, got lots of toys for that.
If its period correct you can run it, the USA is looser on what they call sportman class etc they allow a lot of extras after 75 if it not going to make it faster.
All post 72 will have rear disks, and a spooler front, but mags are only really seen on a few bikes, personal taste, but not many guys like them for obvious reason they look shit.
mostly the Street tracker guys run them on XS 650 stuff. Even the modern still like the VM3.5 rims and spokes.
