AN fittings for transmission cooler lines

I would like to install -6 AN fitting in the transmission case so I can plumb the coolant lines on my 904 away from the headers..

Does anyone know which adapter fittings I will need for the case?

TIA
I put quick disconnects on mine last year when I changed transmission cooler , so simple to deal with during trans R/R and also no more messing around trying to tighten fittings up around shift cable either.
