SR elbow to downpipe nuts

[camwhore]

Been searched.
I need the nut size/thread pitch of the 3 NUTS for the studs attaching the downpipe to the turbo elbow/outlet/j-pipe. NOT the 5 nuts/studs for the elbow to turbo (which are readily available).
I read about and tried a M10x1.25 but they didn't thread on. I will be trying a 1.5 pitch, but was wondering if anyone knew this off-hand?
The elbow and studs appear to be OEM.
Your help is appreciated

truth.
for anyone else who searches...

Personally, I would try to see if they're available through Nissan. The Z32s use the same nut for their O2 elbows, and the factory nuts are usually treated so they don't seize up as easily as an ordinary fastener.

just wanting to clear up some misinformation on this - the correct thread size is indeed 10x1.25.

because i value the search and this is being returned. apologies for bumping a 1.5 year old thread. let it die...
