Splitting the driveshaft and a gearbox q

[Mal]

The long one with inter-shaft, can it be done? I want to dismantle the one I have for my Corolla. Tried to mule one from a Dispatch van apart with no success

Also, what gearboxes are out there I can bolt to a D-turbo that use a hydraulic clutch? I blew the one apart on the Corolla, it's very similar to a BE4 with a few extra holes for mounting points at the rear for the subframe mount. Corolla uses hydraulic clutch, don't want to be pissing round converting to cable

Cheers
