The top mounts only fit one way so you will be totally out ie 180deg out.... You will have to have either custom top mounts made or rotate the turrets as I said. It's not as easy as being symmetrical. I'm not as said trying to pick holes but you WILL have problems down the road when fitting stuff it'll all be backwards. Your best rectifying now than messing about later on trying to get custom plates..
Because the 2 holes are closer it only fits that one way and there are 2 types of top plates so if you fit them you'll be anywhere from 1-2" out...
