Of course, you'd have to test fit the D/C bushing to see if it will work with the SunTour spring and
arch. As I recall the adjustment flats on the D/C bushing were smaller than the SunTour bushing.
The wrench flats don't matter, but length and diameter of the section where the brake arm sits are critical. OTOH, there's a good chance they'll fit because various companies often share vendors and use similar parts.
