Nissan Transfer Case and Differential Fill/Drain Plugs

I have a set of 3 (1 new) drain plugs and 3 fill plugs for 2000 - 2004 Nissan Xterra 4x4 trucks. 1 of the fill plugs has a 1/2" hole in the center; the hole is used for filling the transfer case/differential with a fluid pump. Unfortunately, with exception of the new transfer case drain plu, I cannot remember which of the rest are for the t-case, front diff, or rear diff. They look interchangable, but Xterraparts.com shows different part numbers for each. $10 + shipping to your destination for the whole bunch. Send me a PM if you are interested.

Thanks,
