atc 250r brake hub question

[poohbee1]

201140 I'm trying to replace my old brake hub mine is looking pretty bad. I think the gold one is off a 1985 atc 250r but please tell me if I'm wrong . The silver one looks like the one on my 1986 250r . I was wanting to know if you can put a 85 hub on a 86 and where do the o rings go? I have some 91351-ha2-005

The gold one is definitely an 85. As far as working on an 86 I'm not sure? I've never used the orings.
