I got a NOS Zeus drive side crank arm off Ebay for my soon to be all Zeus frame and components. I am missing the Zeus Arm non drive arm. I have pictures of it I can send off line. It matches the Campagnolo Record Cranks of the 70's. A new of close to new would sure help. Please me contact off chat line. Zeus Lives again! Or soon will. Baron Corpuz of Holland is helping with the project and even has some Zeus frames and components for sale now. Charles Nighbor Walnut Creek, CA
