If you have the five pairs of glasses that used to  come with the projector
you could make a start with those. They seem to be quite good quality with
adjustable temples and glass to protect the polaroid ( although this can
give some reflections) the main problem is that the projector polaroids
although mounted on glass don't seem to such good quality. They give
ghosting and are not even neutral density like the glasses are but a give a
dark blue tint when crossed. While you are changing it you might as well
standardise but there is more work involved in changing the glasses over.

Do not tighten the lens mountings to much the loosness is intentional to
allow for expansion. I have had to replace one lens in a Fed already
because it had cracked.  P.J.Homer
