Hey Stan,
I've got that alternator on my 1970 TR6.
I did the conversion a long time ago though and have forgotten many of the
details.
It might help me a little bit if you could post web addresses to the sites
that you found and used as reference for the conversion.
That might spur some memories. . .
I'd also be happy to go take a few snap shots of what mine looks like if it
helps any.
I seem to recall, however, that I ran a couple of new heavy gage wires from
the alternator rather than use the one in my original harness.
That old harness has enough issues without my trying to pump 50+Amps through
it.
Sorry I'm not more help at this momemt.
Post those website addresses and we'll see what we can do to help.
