Not a fan of having to weld upside down... but was very pleased how my welds turned out where the left/right braces meet up with the main brace. I used LOTS of HEAT!
All finished... I will clean up the welds when I go over the entire floor before I epoxy coat it then truck bed line it.
It was quite amazing to see how much strength these braces put into the floor. (You could really tell when you would stand inside the car... there was NO give anymore.) I can not believe some of the photos out there where people leave these off during a restoration... they are a MAJOR structural piece for the convertibles.
