go see a local dealer who buys parts from Bikes and Bits importers in WA. they have a large range of rods, pistons etc for most models. i will check tomorrow but i think they could do a rod. if not you just get them to fax you a rod chart, you then fill in the dimensions of your rod and fax it back and then they will match it up to a rod kit in their database.
will get you their ph/email tomorrow and they should be able to point out a dealer closest to you
