VDO Hr Meter stopped working

[Mah na' Mah na']

Seems my VDO hour meters have stopped working altogether. Tach is still OK. Contacted Tiara and VDO for replacements, no luck. Anyone know where I can get the flush face mount VDO tach/hr meters for a 1999 40 express short of stealing them from another boat?? In the meantime, I have installed hour meters in the engine room that run off fuel flow, but would still like to get the meters working on the tach.
