HELP!! refilling gearbox oil

i am in a bit of trouble, i have dropped the oil out the gearbox (3/8"square drive) and opened a larger plug (14mm hex drive 30mm diameter) on the end of the gearbox, pretty tight to the chassis, to refill it. is this the right one? i tried sticking my fingers into the hole but it seems not open fully to accept a filler pipe.

can someone please advise…

ok, i have found a mgf website with clear pictures and a nice “how to” for idiots like me!
