I have nearly the same bicycle. It is a 1982-83 model 980 that has the identical frame and just slightly different kitting. Has a 980 gear ensemble instead of NR and 605 arrestor set instead of Flash but otherwise appears the same machine.

I'm with @

If you really want to know, find the worst spot, strip the rust, see what's left. The bottom of that BB looks bad, but they're pretty damn thick. The area around one of the lugs looks pretty damn bad, and starts out thinner.
You might be surprised and find that it's ok.
Or not.
