I'd also be interested in seeing how you'd fit the hydraulic slave cylinder to a 901 trans. Shad's explanation is a little confusing with regards to flipping the clutch arm upside down? Not sure I'm following the explanation here.
I've got a similar problem with a 914 trans. Low clutch actuator arm meaning the slave has to sit below the axle shaft/CV joint area. Problem is I'm going to have some frame members in this area and there might not be room for the slave too. I definitely know the reversing pulley and housing (from the 914 mid-engine set-up) has to go.
Anyone got pics of a working set-up? Pleeeeease???
