I've been able to get a set of double groove pulley's that are for my '60 GMC The upper pulley (waterpump) simply bolts on with no problem.

However, the lower double groove pulley has to be attached to the crank shaft (which to you press on the shaft as normal) How would I go about removing the factory single grove and replacing it with the double groove?

Anybody done this before?

Here is the webshots link for the pictures.

The forsy pictures is the oem single I need to remove off the shaft ans replace with the double groove in the the pictures.

Thanks Jake
