Harmonic Balancer Question

Professional Products has one. But, if yours is new and remarked...5 of 6 holes should line up. You can simply oval the 6th hole so a bolt clears. The change was for 6 even ly spaced holes to 5 even and one unique. But it's close.
That is what I ended up doing. I really didn't want to do that, but it's done now. I didn't even think about checking Professional Products.
