Sounds like the jib pivot point is missing? As a rough guide to where is should be:
Measure the distance from the mainsail fairlead to the main boom pivot point.
The jib pivot point should be about this distance forward of the jib fairlead.
The jib pivot point may have used a rail or channel to provide a range of adjustment
Picture below may help... the jib boom has a heavy duty fishing swivel at the pivot point, the lower end is held by the pin through the channel - the jib boom finishes up about 30mm above deck
