Alternator Clocking?

[jack orchard]

I have 2 gm alternators for two different flatheads, a 10si and a 12si. Can they be "clocked" in a different position so that the connector is in a different place? How many different positions? Many thanks to all.,...jack

Both 10si & 12si can be clocked in 4 positions. http://www.madelectrical.com/electricaltech/delcoremy.shtml
