WTB SB internal balance harmonic balancer

this came off a 70 340 if i remember ( i have a bunch of 340 balancers) its been sitting around for a loooooong time! it needs to be cleaned up, but if you look at the pics closely you can see the the rubber is in perfect condition. 40.00 plus whatever shipping is. if you interested pm me your zip and i'll get a shipping quote today. mark
