No timing marks on harmonic balancer

I had to replace the clutch. Using a Haynes manual I got the task done, but after all was reassembled the engine would not start. I followed the manual marking the distributer position and all that, but the timing is incorrect. After determining TDC I inspected the timing marker on the chain cover it is as pictured in the manual, but there is no mark to correspond on the pulley (harmonic balancer) Do you have any ideas? the timing needs to be 8degrees BTDC, Thank you
