Yes, Sw20 mr2 strut inserts fit - I have rear ones ehre I plan to use in mine with a ~40mm (rough estimate as I don't have stock ones out to compare to) spacer. Front ones are even shorter still, IIRC (it was a long time ago I worked this out) ~60mm shorter. Lots of nice adjustable stuff available for these - I'm got some GAB 8-ways.
Go to monroe.com & have some fun with the online parts ctaalogs and .pdfs of shock dimensions.
i think i mustve been concentrating on the 'monroe dot com' bit and went hurridly off trying to get some dimensions... that said, monroe dot com was pretty crapola...
