contact either Dennis or Ken Dunn (kdhotsaw) there is also walker's saw shop in canada as well as madsen's also dozerdan i believe builds a few.
i have an 066 built by Dennis and let me tell you that it is one bad a$$ saw!!! this saw will run balls to the walls!!! its the smoothest saw that i've ever run, i would highly recomend that you give Dennis a call:angel: i'm planning on sending him a husky 346xp in the next couple of months
