Replace oil filter housing?

[papasmurf]

I am in the middle of an oil change on the car at the moment and was in the process of removing the old o-ring from the filter cover when it slipped out of my hands and hit the ground. The spring loaded piece inside at the bottom of the filter cover popped out and one of the three pieces in the bottom of the filter cover that seem to hold and center this spring loaded piece broke free and fell out. It seems the spring loaded piece stays centered for the most part unless you really try to push it out of the way and I would guess that the filter would have to stay centered due to the piece that goes through the center of it connected to the block. Is the cap needing replacing now or is it not that big an issue? I have not put anything back together yet, but the chances of getting a new cap today locally (assuming it even existed) is too late.
