@66340SEDAN You said, “drill one hole bigger.” Is that due to the offset hole in then pulley?
Otherwise, the pulleys lined up OK?

Whoa! Separating a balanced is pretty brutal. Wow!
I did take a quick trip through summit to look at the ATI pullies and noted some with and without hubs. Which was a surprise to me. There was a lot of different versions.

The was also surprised by the trick flow pulley there. That I just found out today for myself.

Aligning pulleis can be maddening.

I separated one years ago, but it was a stock balancer on a VERY HOT Chevy 327 and you KNOW how those like to rev. That little motor saw 9K more than once. After the stock balancer came apart, I put a sho nuff Fluidampr on it.........this was before you could get any of these import parts. Probably about 1986, I would guess.

The balancer is one of the places I've learned not to cut corners on. A stock Pioneer replacement just "ain't enough" for most builds out there.
