The owner didn't want to cut into the floor to keep the connectors full depth. Because of this, I had to cut the connectors to the contour of the floorpan. I did re-box the areas that were cut down. I'm unsure of how effective they will be since they had to be cut down to almost 7/8" to remain flush to the Bottom of the frame rails front and rear. They are welded at three sides on each end.
