engine mount probs

I`m trying to replace the lower right engine mount on my 1999 volvo s70 awd but I cannot find the mount. Ive went to parts stores and had it ordered but its always wrong. The mount I recieved has only 4 bolt holes but the mount that is in the ccar has 6 , two in the frame and 4 in the engine. I believe that the engine might be from a different car because the mount is much larger than the one Ive bought a couple times and is much larger than the frame.. If someone could help it would be a great help since my gf started a new job but am having to pay someone to take her to work cause my car is down.
