Yes the tube stub mounts at the extrusions is the same geometry - the extrusions are at the same angle but have an additional wood wedge inserted to accommodate the slightly wider angle of the longerons due to the wider fuselage.
The Long Ez mount (whether Cont / Lyc conical or dynofocal) usually has thicker wall stub tubes than was called out in the Cont O-200 engine VE plans.
