What timing cover are you using with a 7.3 inch damper

Ok, I’ll add I have a late model water pump too. Maybe I’ll re ask the question “ what timing cover do I use for a 7.3 inch balancer”….
May have already been said but just set the motor to TDC, find a spot where you can bolt that thing somewhere else on unobscured and remark the balancer for TDC to line up to its zero mark.
