Loading bar, trying to attach a pixel shape to the end of my load bar mc

Hi all,

I have a loading bar setup built with 2 objects.
My load bar and the loadbar housing, it works by.

loadBar._width = loadBarHousing._width * (percent / 100);

Now my problem is that I would like to add a 2pixel line to the right side of my loadBar_mc and make it sit to the right of the loadBar MC all the way until it completes the fill/load. Obviously I cant just add the shape to the loadBar_mc because that will resize.

No sure on where to go from here.

I have a file here:

If someone with knowledge on how to do this could help it would be really appreciated.
