just as bullet said!
drill that bitch out!!! and the real option is to get an e36 m50 mount
. please be careful with that drill!
...hmmm.....wonder how that mount arm will line up. oh by the way, make sure your engine mounts are LOOSE and flipped backwards as in 180* degrees horizontal rotation. you will find that it wont line up, then you're going to freak. just have a 2x4 on hand, cuz you will def need to pry here and there to get the mount to line up with the engine mount arm hole!!!
