ok, i am in the beginning stages of working on a rear disk kit for the trx300, have figured out some of it but need info. is there any rear disk atv that used 34 spines to mount the rotor bracket to the axle, if so what? also need old broke parts for fabrication with. back plate for brakes, an old rotor mount if possible. trying to figure out the brake side bearing assembly too. any suggestions would help and really need that info on the rotor bracket. thanks for any help everyone.
