Brand new TCI Rattler harmonic balancer # 870004, BBC, internal balance, has been double-keyed (1/4" & 3/16"). Also included is a PTO for snout-driven applications such as v-drive circle boat, 1.375" diameter male output shaft, 32 spline. All parts are brand new (both components and the fastener hardware) and never used or even fit to a crankshaft snout, just a bit of scratched paint from handling.
These two components can be separated (see pictures) and the balancer may be used separately.
The balancer retails for $340 new.
If you will use the PTO then you are that much farther ahead again, and if you will not use the PTO then you can sell it and be much farther ahead that way.
