'78 front suspension

[Gene]

I have a '78 Bus with its nose in the air. The "Previous Owner(s)" had jacked up the front suspension to the point that it is almost6 inches above level. It is almost completely topped out. How do I get this thing back down to level? While it is OK for off-road, I think it may ride better on the street? I don't see anything on the beam that looks like an adjust-a-drop like you would see on a Beetle.
