Today I welded on the front end of the driver's side heater channel. I welded up the tab on the front of the heater channel, I welded the bottom of the dogleg shut, then tacked and welded it in place. I have a bit of a challenge with my driver's side floor pan, so I am not sure I have the dogleg exactly where I want it. I'll take a closer look later in the week. Hopefully everything will be ok.
