MK7.5 R Variant rear valance/diffuser

[XtremeGSW4mo]

After hours of searching, I couldn't find a definite answer.

Why won't the MK7.5 R Variant valance/diffuser fit a MK7 Sportwagen? Is it because of mounting holes or dimensions? Has anyone even tried to install one on their MK7 Sportwagen? Looking for an explanation on why and if there is evidence.

The MK7.5 R Variant diffuser looks like it has some aero benefit to it due to the angle of it compared to the MK7 R's diffuser...so I am not interested in the MK7 R's diffuser. Thanks in advance.

Mk7 and Mk7.5 have different bumpers. Look at the photos below, reflectors are part of diffuser on MK7, and built into bumper on MK7.5 along with some slight differences in bumper shape.
