Thanks Richard.
Here's my 79 with an alternator from a Chevy pickup driven by the chain.
That's interesting... I can't tell from the pic but is it driven by the final drive chain, or is the there a sprocket on the cam/crank shaft and a separate chain driving the alternator?
I'm thinking the latter so you have constant rotation?

I never got around to doing a build thread so here she is.
