As much of a pain it is to take the shoes off again, you will be better off putting the star adjuster in and replacing the "H" bar that came with your car.

When you put the adjuster in, screw it all of the way down first and make sure the cable is loose. Use a screwdriver and spred the adjuster until the shoes touch the drum, then back off 1 notch. Do this for both rear wheels.

When done, adjust the center console handle.
