Can't Find Tools To Fit R180 Drain Plug

[aircobra]

tried to change in oil, but the diff drain plug ( 1/2 square "?) is just behind the rear crossmemember. so can't get either a socket driver or a cross bar in there.  seems to be ~5mm short of space

do i need to drop the rear cross member to get access and leave the diff hanging by the moustache bar? is there some tool i need to get?

If it's anything like the later Nissans it would be a 13mm square and not 1/2".

 

I nearly destoryed the fill plug on my old R33 trying to open it with a 1/2" ratchet because the difference in size was enough to round the hole.

It's all Japanese to me

Just stick a jack under the diff, drop the moustache bar out of the way, and a 1/2" socket handle - that's always worked for me; you could always slip a metal shim in alongside.....

lots of scary stories about people using the 1/2 and wrecking the plug

with the second design will have to drop the mount

Alum foil and ratchet. Has never failed me.
