I've recently bought one for my 2wd Saph (£90)...... 2wd one is still available, but the 4x4 one isn't (so I'm told)

not sure what difference's there are between the 2wd & 4x4 pipes....... could just be the length???

I work for a hydraulic's company that makes hose assemblies..... I looked at making a hose myself, but the end into the rack is "special"..... pump end is just a banjo & I have them in stock

The other idea I had involved tapping a thread in the rack & do away with the "special" end

......

If you can't 4x4 pipe maybe something could be put together by a hydraulic hose company using the rack end of a 2wd hose as a starting point
