I picked Up this flywheel a few years ago as part of a top loader setup. I plan on using a toploader in a 50oz build soon, and can’t tell what the balance of this flywheel is. It’s a 157 tooth, and has 6 holes for a long style clutch. There are no markings anywhere to tell if it’s 50oz or 28oz. Can it be determined from the balancing holes in the backside what this is? I’m hoping it’s a 50oz, as that’s what I need for my build.
