Specialized Drop outs?

Hopper of rocks

hi there. was just wondering if anyone would know about the drop outs on a pre disc P3. the 2000ish black and red model? its just because i am wanting to fit an A2z non disk adapter to it and cant remember if the drop outs are flat and if they are vertical? anyone know if the adapter will work? i cant check because its at my parents house about 200miles away...

thanks in advance!
