Ati balancer

How about more information? Engine, transmission, type of driving, etc. The crystal ball isn't working today.

Sorry but didn't think any other info was relevant for changing the harmonic balancer. It's a racecar (drag) that's why it's in the racer forum. 727 trans but again what does that have to do with the balancer? As stated above small block, 360 based.
