I understand.
a french member of this forum (michaelovitch) made a tutorial for the D24
here's the link :

He unblocks the crankshaft nuts with a big bar, letting it laying loose while doing the rear with the tools, then the front (because the rear is done, the crankshaft will not move ) .
The crankshaft special tool is veeery hard to purchase on the net! I hope I will find it, otherwise I might follow this tutorial.
