Subframe connectors for a driver/cruiser, necessary to weld to floor?

Heres mine. Slotted at the rear and overlapping the framerail. E brake cable rerouted inboard of the connector so it runs parallel to it. I have seen people make big gaping slots in the connectors for cables. It kills the strength and looks like ***. I fitted this with a 4 speed setup. It clears the Zee bar well. Note the homemade torque boxes.

What did you use there? 2" x 3"? you did a real nice job! Perhaps what the factory would have done. Certainly what they should have done!
