Photos Sub Frame Connectors

Does anyone know if 2x2 tubing or 3x2 with the 2" side vertical would be tall enough to contact the bottom of the pan? I was thinking about connectors but i didn't want to cut up the floors, and i figured that welding to the bottom of the floor pan would be better than not touching the pan at all

Your right,it would be stronger especially if the frame connecter has a "foot" like the original frame longitudinals. I also dig the idea of sectioning the end of the connecter so it slips into the longitutinal at least 6". A foot would be better as it would really strengthen the cowl area.
