I only know of Pug / Cit that use this clutch - and I think they discontinued it after the TD was stopped. The HDi uses either a standard push clutch (90BHP) , or an even worse hydraulically operated pull clutch
Anyway, getting the clutch back together is no real bother with a lift. Sling the box so that when it is lifted it naturally hangs at the right rotation and angle (I can't remember exactly how we did it, but sling it from a lug near the top starter bolt, and a lug at the back outside corner, then add another sling to the outside end of the box). Hoist it back in and offer it up to the engine. If you made an alignment mark a la Haynes set the release fork to this position (ah no, just realised you won't have, since the release bearing was broken free....
A second pair of hands is v useful at this stage if you can find someone to help for 1/2 hour.
I trust you are replacing the two nylon bushes top and bottom of the release fork, and the input shaft seal and tube whilst the box is out....?
Edit: Just looked back over your photos. Before refitting the box, remove the RH drive shaft output housing (where the speedo plugs in). There are just 3 13mm bolts, and a flat O Ring in the back - however with this removed it makes life sooooo much easier to get the box back in - it also a piece of cake to reconnect the speedo pickup before you bolt it back on. Watch out for the speedo drive which will fall out when you remove the housing
