Transfer case fill plug bolt size

[ItchyRichy]

I can't seem to find the right socket to loosen the transfer case fill bolt on my 86 GWAG with the NP228 case. I can break the drain bolt free with an adjustable wrench, but I can't get the fill bolt free. Anyone out there know the right size socket?

Gotcha Itchy...
Aren't those things the BIGGEST PITA???

Its a 30mm socket. Found one at the ACE Harware.

Good luck smile.gif
