Which V6 Donor

[Allora#2]

Hi Tom,
i am not sure if an 24V will fit in an Allora?

i have the 12V in my Allora and to the bulkhead are only 2 cm
and also to the rear frame are only 2 cm space! look pic:
please take the measurements from an 12V and 24V engine.
And it's necessary to but it lower in the engine bay!
otherwise the rear clam did not close! it lies on the inlet manifold!
