Anyone know where to find information on Sandvik forestry products, specifically harvester sprockets? I found some NOS units and the seller claims they are .063ga but that doesn't seem right for 11 and 12 tooth sprockets. I don't even know of an .063 bar that could run a sprocket that large. I'm hoping they are actually .080" but can't find any product information online. The models I'm curious about are the 2RSC-11 and the RSC-12
