I mucked about for ages with clothes peg wedges, little bits of wood and cardboard until I got fed up and made this thing.  Two pieces of angle bar drilled and attached to the port with four bolts drilled and tapped through.  It took about twenty minutes to make this and saved ages in messing about.  I can simply screw or unscrew the end bolts to adjust the position of the ports into the correct place.  No indication on the plans about how far to set these in, so I just put it right in the middle which looks right to me.
