FLUIDAMPR SB MOPAR RACE 318 340 360 LA Internal 7.25 Harmonic Damper BALANCER 720301. This balancer appears to have never been used, no Marrs or marks whatsoever from an install, just a little shelf wear from being moved around. This is the early version before they went to six bolt holes. The three bolts are a tad larger and require slight enlarging of the three holes in the pulley itself. Same goes for the six hole, you just have more holes to expand!! I would suggest this for race applications due to the thickness and for a stock/modified use it will require a shorter pulley, half inch AT MOST! Ask any and all questions, nothing to hide, it’s a simple part and all is visible in the pics! Thankyou for looking, $215.00 free ship in the lower 48!
