I sure am! I was kindly given the 8/9 rear struts and springs, but didn't have any 8/9 fronts. Found some stock evo X fronts for sale cheap and bought em (months ago). As far as all my measurements are concerned, the fronts seem to be nearly identical to the 8/9 evo fronts. The mounting holes are the same size and spacing. The mounting ears are also the same width apart. The top hats are a 3x120 pattern, so I opted to get camber plates and now everything is ready to bolt on.
HOWEVER... I'm not at home and the nearest GVR4 belongs to Tyler over in Ft. Drum and its been broken forever and getting it over here for a test fit is not a possibility.
I don't think evo X rears will work because from the pictures that I've seen they are a lot longer. I'm sure they would 'work' but would give you a nose down look to the max.
