Q - TR3 alternator conversion

[ccamley@mmm.com (Chris Amley - 3M Co. - St. Paul, MN)]

Subject pretty much says it: without considerations to Authenticity, is
changing a TR3 to alternator a Good Thing?  How do you do it?  It's so
sad to see the ammeter needle barely able to drag its sorry little self into
the right side of the dial whenever I turn on the headlights (which, lately, I
do whenever I drive the car)!
                            
Thanks,
Chris
