This is a harmonic balancer for the Mopar big block engines, using a Forged crank. Very good condition. Rubber doesn't have any cracks, or deterioration to it at all. I soaked it out in a pail of Evaporust solution to bring it back to bare metal condition. You paint it up any color that you want, when you get it. I think $50.00 would be a fair price to sell if for, in the condition that you see it, in the pictures. I'll send it out to you in a USPS flat rate box, at $15.00. Payment will be thru Pay Pal. Serious buyers, send me a pm. Thank's a lot. Jim V. hemi71x
