i just have a quick question about the thread pitch or the stealthmode oil drain kit... the nipple fitting that threads in to the block / oilpan. can anyone confirm what size it is? i just need to know before ordering. thanks.

Threads on the block 1/8bspt
threads on side of block fitting 1/8npt
threads on t3's and t3/t4 1/8npt and sometimes 1/4
t3 drain flange thread 1/2
T25 and 14b drain flange thead 3/8
My prefered threads bugle boy

 

thanks. i meant the oil pan fitting. but i already have my answer. ordering soon.
