1969 Barracuda 340 Formula S Restoration
I didn't like the looks of the rubber sandwich layer on the 52 year old harmonic balancer. Found out it can be rebuilt by a company called the "Damper Doctor"

REBUILT HARMONIC BALANCERS
Rebuilt harmonic balancers have a refundable core value. All rebuilt harmonic balancers are first disassembled and cleaned. The parts are then inspected for defects, including stripped bolt holes and worn or cracked keyways and hubs. Harmonic balancers are then prepared for assembly. Timing marks are set to the factory specification by using a laser aligning process. After the timing marks are set, the harmonic balancers are then injected with a high-temperature, high-strength silicone rubber that is then platinum cured for a extremely strong hold. The new silicone rubber is capable of withstanding temperature in excess of 450 degrees, and will hold up against pressures as high as 770 psi. Rebuilt harmonic balancers carry a 3 year limited warranty
