Wow, that's quite the rustout.

Your holes were up near the top, just under where that steel clamp braces the 
tube, not down under the rubber grommet, but I've never seen anything like this 
in the rusty salty midwest.

I had one where the little overflow nipple rusted off, and I took that one out 
and brazed in a new pipe there. That one also got brass on the cap sealing 
surface, but only because it was out of the car already. I think the rest of 
that pipe still had it's black factory paint over most of it. Nothing like the 
rust you show in your photo.

Lead, or brass, would prevent any more rust thru. I should have a couple of 
good '71 necks somewhere, but that's something I've actually never needed, so 
I'm not real sure exactly where I would start looking for them.
