Or, just put a new balancer on it and check timing.
Is there a reason you're doing the chain?
I'm going to recommend a step to clay68c10's post. Hopefully everyone is okay with that.

Step 4 1/2. After installing balancer verify the TDC mark on the balancer is lined up with the mark on the timing tab. If not then verify the timing tab is not bent or modified. If the tab is correct then the outer ring on the balancer has moved in relation to the keyway in the snout of the balancer.

Generally you check this before installing the balancer completely, just incase you have to remove it. Or you can compare your balancer to a known good balancer before installing to verify the outer ring hasn't moved.

More information on balancers in this link.
