It hould be very simple. You would need a different bracket to support 
the back end of the alternator because it's shorter than a dynamo. You 
might also need a different fan belt because the alternator pulley is 
smaller that the dynamo pulley.

Then just rip out the regulator box and associated wiring. The 
alternator just has three connections: battery +ve, reference (usually 
routed to the battery +ve or starter solenoid) and ignition light -ve. 
The other side of the ignition light goes to the ignition +ve supply.
It should be the same for any classic -ve earth car. If you have +ve 
earth then you'll need to switch over to -ve earth, which will affect 
any electronic equipment such as the radio and tacho.
