Very basic question from someone new to Volvos.

Do all P2 platforms have all mounting points for all engine/transmission mounts?

Or, worded another way, could I confidently buy any V70 whether XC or not, and mount two/four wheel drive running gear? And would there be pickup points for all possible engine mounts?

And, on a side note, is the bolt pattern for 2.3 and 2.4 engines the same? To the gearbox, like.

Thank you
