250R swingarms

[2strokes4life]

i just picked up a 250R but im not sure if its a 85 or 86 and im trying to figure out what options i have for swingarms. im assuming the 85 swingarms have different bearing carriers from the 86-89 trx/atc 250r's, because they list the 85's seperate. is there a difference in length on all these years? can i use anyone of them with the right carrier? thanks

the way the rear brake mounts is also different. the 85 has almost like a linkage arm that extend toward the bike not sure what it does becaue i dont own an 85.
