in new construction, typically i would put a strip of plywood or
whatever against the fascia, install the strip vent, and then put the
last piece of plywood on. the flanges would go against the bottom of
the rafters. i have seen it retrofitted where someone cut a two inch
strip and put the vent in upside down. looked pretty bad, though
soffits don't get a lot of attention. another alternative would be to
cut the two inch slot, put the soffit vent on so that the flanges are
on the soffit board (below or outside of the board), and then use trim
(1x1 or something like that) to along either side. heck, you could cut
your slot, put in hardware cloth (spraypaint the cavity black) and then
run two strips of trim on either side. i've done that on high end
houses.
