I've acquired a set of the replacement z bed hinges that raises the
Westfalia lower bed about four inches.  I'm installing them to gain some
additional storage in the rear, under the rear mattress.  Everything looks
straight forward but there are a couple of pieces included, the
purpose/installation is not obvious.  Does anyone have (or can point me to)
a diagram or set of instructions for this installation, or anyone that has
done this and can answer questions?
Any additional info would be appreciated.  Oh yeah, obviously, not
instructions came with them.
