What else to change when swapping gearbox?

As per the title really, i've sourced an M2B4 and would like to take full advantage of the opportunity to change whatever else i've got access to at the same time. I've got a rear main seal for the engine already and will be changing the clutch at the same time but is there anything else I can do with?

TIA

Flywheel if you're after a lightweight one.

Might pay to do the driveshaft seals (seals where the drive shafts enter the gearbox) before installing

yes second the lightened flywheel suggestion
and also rear engine mount - it will be easy to access with gearbox out so id check the mount is in good condition - could also think about polybushing it or using some pu adhesive like tigerseal to stiffen/shore it up if you plan on adding more power or going out on track in the future - might be worthwhile having a look at the front engine mount as well but that can be done anytime and this is most common mount failure but replacements are cheap
