DIY floor pans.

Those look really good. Nice job!!
Another question in the area that goes across the frame section would it be best to drill holes in the floor pan all the way across and weld it from the top or go under the car and weld it from the bottom? Or both?
Just welded on top don't make life difficult LOL I still got big fish plates welded in my duster from when I had my roll bar.. carpet covers all that stuff..
