It mounts between the center of the car and the front subframe. I would guess the bolt holes are there, but I honestly have no idea if it will fit a V70 AWD. The only car I know for sure it fits are the coupe and convertible C70.
If you want to look under your car for the bolt holes, I will be glad to measure out the center distances so you can see if it fits.
some quick googling shows me that it probably won't work on AWD cars due to the driveshaft and exhaust sharing the center tunnel, one of them would pass right through this bracket.
