Rear wheel drum lining

[Finesse150]

So I advance my rear brake adjuster way past the limit and figured it needed new pads. Upon taking the wheel off I measured the drum lining and it’s at around 153mm. Is there any option besides having to buy a new rim or that’s it? Much appreciated for the help also random I’m sure I’ll have to search for but I have a 1980 Suzuki gs450L that rear rim wouldn’t work I’m assuming. My Nighthawk is a ‘97 750.

Drum lining 153mm about 6 inches?? Is this the diameter of the drum??
