6-cyl harmonic balancer/pulley/rubber broken

[Agv63]

Hi. Last time i got was from ebay, partsgeek was the seller. But there is others. 12bolt tom should have as well, pretty sure summit and jegs as well. The double v is most common, and cheaper from the single v when i looked at it last time.
V8 unit sits more away from engine, and a pulley can be machined to fit from backside but taking it off in future would be a real pain, (as me how i know).

Cheers.
Adriaan.
