Alternator for TR4A?

[DLMAssoc@AOL.COM]

Amici...

I want to add an alternator to my TR4A, and quickly... is there a specific 
model that's best suited (read - cheapest and easiest to install) to the 4s?  
Since there's no wiring harness, lights, etc., to worry about, I assume I'll 
want a single wire, lightweight job with integral regulator.  Can I use the 
original generator bracket or do I need to fabricate something new?

Thanks...
