I need to find information about mounting a Toshiba TDP-S8 projector to a ceiling.?

I purchased a Universal Ceiling Mount kit from Toshiba and it doesn’t fit my TOSHIBA projector. I have called them and they don’t support the “accesories” nor do they have idea what I need to mount this projector. The model is TDP-S8 and any information would be appreciated!
I need to know how its suppose to be mounted…like which holes on the bottom are for mounting? I have different sized holes in all different positions. There seems to be NO instruction anywhere on how to do this correctly.
