So, I put my 69 on a lift for the first time today since i got it,, everything looked great except for the power steering cylinder (leaking by the seals and no boot) and the damn tranny cooler lines going into the radiator.. Its leaking about a drip every 30 seconds if i dont touch it, but when i move the line it runs out.. Its loose at the seam of where the line actually attaches to the radiator,, now how can i fix this,, i couldnt see very well under there because of the light from the windows, but can i replace just the nipple or does the whole thing have to come out? Damn car..

 

Replace the radiator or take it to a radiator shop for repair.

 

If you are talking about the female end that is brazed to the radiator, then you are going to have to either braze it yourself, or take it to a rad shop. If you are talking about the male threads are leaking, then try some teflon tape.
