I've been doing a bit of reading.

The pumpkin is from the IS, but the differential itself is very likely to be the same one that comes in the IS-F. The IS-250/350 have open diffs as far as I can tell, while the ISF comes with a torsen. Aftermarket-wise, there are currently replacements available from OS Giken and Tom's. And if the ring/pinion gears are as strong as those in the IS's, there shouldn't be any need to worry about it's strength.
