ln106 gearbox/transfer case breathers

[wellsie24]

im looking at extending the breathers on my 1990 ln106 dble cab which is a import but i cannot find the factory breathers on the gearbox i have taken the centre console off and everything i can see something that looks like one just in front of the gear lever on its base plate but cant find one on the transfer case i have looked in my haynes manual it doesnt show where they are also i have been told that they may be vented through the gear levers i have also searched high and low on google but cant find anything

has anyone found/know where the breathers are on the transfercase/gearbox or are they vented through the levers
