I have an 86 trx250r. I was wandering if anyone could tell me the sizes of the o-rings that are in the back end. There are five of them. There is one under the brake rotor holder, one under the brake caliper holder, and three around the axle carrier housing inside of the swingarm. I don't have the old ones so I can't take them in, and at the honda dealership they could only give me honda part numbers. Thanks
