Pulley/Harmonic Balance question....

[tomps]

Making pretty good progress on my Challenger and the 383. Started dressing it and it's going good. I recall when I removed the pulley from the harmonic balance it was missing a bolt. Didn't think much of it at the time but I see why. Can't seem to get it lined up (I'm guessing that's why the previous owner left out a bolt). Tried rotating it in every position but still won't line up. Notice the "bottom" opening is off quite a bit. Any thoughts? Was thinking of drilling out the opening a bit more?

there are 2 different bolt patterns this is not unusual , opening up the one hole a little will get all 6 bolts to fit , or you could order a new pulley , the first option is obviously cheaper

Ahhh......2 different bolt patterns...I wasn't aware of that. Given the price of pulleys I'll definitely open one hole up a bit :icon_winkle:

Thanks for the input!
