Found this with a bunch of parts I bought at an auction along with some Mickey Thompson Hemi parts. Appears to be a harmonic balancer but I never saw one with splines. Looks like it had rubber inbetween the 2 pieces at one time. I wonder if it could be from a motorcycle since the auction had a lot of Harley and old Indian MC parts. Check out the pictures and give me your 2 cents. Thanks
