China Bobber replacement clutch cable

[humanbeing]

Hi
You got any connections where to find a disc for my bike? I'm in Nanning and locally nothing Toaboa draws a blank and some local boys in a bike shop can't find one
It's a 150GY off road with 17" wheel heavy duty hub and 6 bolts to mount it
It's about 26-27cm in diameter
Please please advise any solution?
I can find 5 bolt but nothing 6 bolts

Maybe similar to Suzi GZ150 / GZ125HS .
