I have a 2000 ranger and am looking at a brush guard for it that a person is selling from craigslist. I'm not 100% sure how it mounts though, and the person doesn't know exactly what years it is for, or if it even mounts as is or needs brackets. Could anyone give me some help and tell me what you know?

 

That kinda looks like it's for an older model ranger, not 98+
As for mounts, yes it'll need mounts that go on the frame which the guard attaches to

 

It looks like you are missing the pieces that bolt to the frame. The guard will then bolt to that.

 

I have the same thing. I got a nice rhino brush guard (the thing was 500 new and its nice) with my ranger, but I have to get mounts. Ill probly just fab some up once our ice pit here in Ohio thaws out. Its miserable trying to work on your truck when its 10 degrees and the garage floor is even colder.
