I have a 150G and might be replacing the rods very soon. If I do it will be with new ones since they're worn and I don't want to just replace them with other worn parts. I'll hopefully know in a few days whether it'll be necessary (or whether other things will fix the shimmy problem). If it is necessary to replace them, I'll have a set available. Don't know whether they'd fit your K model.
