you will need to ream/drill for stainless steel tubing to have a final fit into the radiator base (hole is drilled in base but is just a little tight for a perfect fit. Reaming is needed)
threading is 3/4″ x 10tpi
if tubing is slightly loose, you can squeeze tube slightly to make a snug fit
Loctite 680 is recommended for the final holding in place of stainless steel tubing
1″ diameter, 1.5″ tall including threaded area
