V8 Quattro Transmission install in 200

I'm still trying to get lines and fittings to adapt to this V8 transmission.  I source a
set of lines from Chris at Force5, but they must be from a different version of car as
the lines don't bend in correct dierctions.  That is OK since my plan was to make lines
if I can source the fittings.

However, even these fittings don't seem to mate easily.  My question is:  How much of a
force fit are the lines that go into the V8 Quattro five speed transmission - model
years are around '92.   The hole diameters are around 12mm.  The hole in the rear of the
trans has no O-ring - just a drilled hole apparently and a bolt hole to keep the line
fitting in place. 

The hole in the oil pump - located near the axle flange, is similar size, but has an
O-ring.  I have one line from a car - I don't know where, but this seems to be correct
line.  It is a braided line with straight pipe and an o-ring recess.

I know I'm lacking information on this project.  It did not occur to me that the
transmission oil cooler connections would use anything but a flare fitting or some
fitting that screws in to the pump   The fittings on the lines I got from Chris seem
more like Air Conditioner fittings.

I'm wondering if I am making up my own lines, why not tap the rear return line and
install a barb or nipple fitting. How much pressure are we talking about here?

Any experts by BTDT means or other school or knocks?
