I have an 86-87 GN Engine I'm building and I broke the harmonic balancer.  I have another balancer but it didnt come with the reluctor for the crank sensor.  I took the one off my old broken balancer but didnt watch how it came off.  It will fit on the pulley 360 degrees obviously but is there a correct placement as to where to set it?  Any help would be great, thanks!!
