At least on the block the pattern is the same i'm sure, the lower half bolts in the sump will be slightly different due to needing different shape sumps, bit i have it on good knowledge that the 5 bolts holding gearbox to engine block are enough to cause no problems, only 3 from my alloy sump wont line up.

So in theory, any IB5 or BC box should fit, driveshafts permitting, if you're willing to leave a couple bolts out when they dont line up, since the block is a hefty chunk that the majority of bolts will be fixing to.
