Thanks guys...thought I had the most complete list but quess not

Yes it was the driver side.

And it has not come back since I had the tube welded on.

The place that did it (C&D Welding....in your backyard Charlie!!) was outstanding. They do aerospace and weld ANYTHING. The guy showed me where the Kooks (he called it a POS) weld never penetrated the header primary . They were able to do it on the car but it took 90 minutes...very difficult acces and part of the welding had to be done with a mirror !!!!
