Mr Dodge, adding the front down bars will not hurt anything and actually help unibody mopars greatly. They help tie the font section to the back half through the cage. The added weight of those two bars is nothing. Unless this is a rare valuable car add them.

blown, no offense as your work is very nice but all those fancy bends have greatly reduced the structural integrity of the cage and created failure points if something serious should happen. I also question if you will see any benefit at all with your front bars as there will be very little longitudinal loading of them. It appears in the picture that any load will be transfered into flexing and a radial load where they are welded to the plate on the door frame. To be effective the compression and tension loads should be transfered longitudinally through the bar to the cage.
