LS460 STI-r lens swap/glass filing question

So I got some STI-r lenses for my LS460 projectors the other day. This morning I went to install them and try and tune them up. All of that came to an abrupt halt when I tried to put the clear lens in the holder, and the lip of the STI-r is much bigger than the stock lens holder. What tool would I need to modify these to make them fit? would it be easier to file down the lips on the lenses, or shave the lip on the projector housing itself so it will match up to the new lens? any help is appreciated!
