This kit seems to have been designed by people who hate Viewsonic. The screws are the wrong length no matter what rack combination you use. Two screws were missing and the ones supplied were metric with no indication of what head size would be required to drive them. This kit is completely unsuitable for Viewsonic projectors. After hours of trying to get it to work I'm not sure if I want to return it or burn it. Either way, it's pure garbage. I can't imagine that all these positive reviews are genuine.
