LA pulleys not lining up with Magnum Balancer

Gimike812 said

The balancer is off a 95 5.2L out of a RAM, the pulley is off a industrial LA318 from a 70s dump truck, no matter how I turn the pulley I can only get 5 out of the 6 bolt holes to line up. Is this common? I am thinking just slot the hole to make it large enough for the bolt to work.View attachment 1715484834

Yep, normal for what you are doing.
I ran across that exact issue and just egged that hole to line up.
Never had any side affects from it, and couldn't imagine there would be.

Really the only other choice is to leave out the bolt straight across from it for balance and I didn't want to do that.
