The SVO had a disk brake 5 lug (7.5"). The only drum I recall is the Mustang, Ranger and T-Bird. The T-bird and Mustang were both 4 lug. In 1994, the Mustang went to 5 lug with disks and the width of the track is wider, but the housing is the same width. The 1993 Mustang Cobra had 4 wheel disks, but were 4 lug.

The conversion is pretty easy and cheap.
