[Spits] Drilling a Spin-On Adapter

[Todd Bermudez]

Hi,

I'm told that it is possible to take a spin-on adapter
for a TRiumph 6cyl engine (not currently tapped for an
oil cooler) and drill it for the fittings.  I'm after
the size of the fittings and the thread count/pitch on
both sides?  Has anyone done this already?  

Cheers,

Todd Bermudez
