Harmonic balancer??

Assembling my engine last night. I installed my 67 273 timing marker on the water pump and it put the stationary degree indicator on the passenger side of the engine. I put my piston stop on and found TDC and marked the harmonic balancer. All the advance marks engraved into the harmonic balancer are on the drivers side of the engine and I see no way to time the engine. It is an aftermarket harmonic balancer supposed to be for my engine. I am looking for suggestions of what I should do? If I had a timing pointer that set up on the left side of the engine everything would probably be correct but the stock one wants to show on the right side unless I install it backwards. Help!!!
