Kevin,
That's pretty much correct. For more info, see <<

I'm running a Crane XR700 in my '71, with a Lucas Sports coil, and they've
been in there for about 10 years with no problems. If you want to use the
ballast that comes with a coil you've bought, make sure you delete or bypass
the exisiting ballast that came with your TR6 if it's one of the later models
('73 - '76).
If further info is needed, let me know.
