Disc and drum axle flanges are different, and you can go from a drum to a disc setup but you can't go in reverse. The reason is that the drum flange will have a taller upper portion which has a big hole for the wheel cylinder to bolt to, a disc rearend flange will not have this part so you can't install the wheel cylinder to it. Look at this thread that covers going from a drum to disc:

Notice how the poster cuts the top portion off of the drum flange, you need this part to install the wheel cylinder. If you don't have it, you're out of luck. Just keep the discs.
