to the asylum.There is a lot of information to be garnered from various people on this site.
There are a couple of '60' guys on the forums. I'm sure as soon as they see the post they'll be along to help you out.
If I recall correctly. This is a subject that has come up before and the answer was that the '60's' don't use the external tanks. Not positive, but that is what I recall.
Anyway, welcome and Sal or Mog will be around.
