Casing Half Stator Plate for MINARELLI vertical

I'm rebuilding a 1995 Aprilia SR 50, with an air-cooled vertical Minarelli engine on it.
The engine case is broken on the stator plate side and i wonder if part number AC093015 will fit.
Looking at the picture it seems very, very similar, but then again pictures can't be trusted.
I already sent an e-mail to the guys in tech help, but maybe someone did this already and can help me first :)
