I am new to 250r's so I have a lot to learn. Anyway I picked up a 250r built to a 350. I am trying to fix all the little things that is wrong with it. I noticed that my rear brake stay has movement and under further inspection and comparing to parts charts I realized the bushing is missing that goes on the pin to hold it in place. Is there I different brake stay that I can use or do I have to spend the outrageous $35 for a new bushing. I would like to also get a crf450 front caliper to run in the back
