how to remove fill plug of D2 T-box

I have a very tight fill plug of transfer box of 2004 D2 td5. Since it is small room and the handbrake cable is in the way, it is hard to get swivel wrench, T-bar wrench and UJ wobble socket to do this job. Can anyone recommend a tool? Is it possible to loose handbrake cable for more space. Thanks!

I found that removing the body helped greatly in this area.....
but I wouldn't necessarily recommend it in your case.

I normally leave the handbrake off, this allows me to push the cable out of the way of the filler plug and I use a 1/2 inch ratchet on the plug it self. It's a little tight for space but very do-able.
