Crank Shaft Pulley Diameter

[RyanBambach]

Hey all, its been a long long time since I posted here. Anyway, my I am needing to find out the diameter of the crank shaft pulley. Not the outside diameter of the ballancer but the actuall pulley diameter (that the belt runs on). I am in the works of a conversion here and need it to set up a tach and alternator.

Any help would be great and if you could give me the measurements I would be very happy.

Thanks in advance...RyanB
