I am trying to restore a Data East JP and the main issue I have is that some parts of the Dino Assy are missed, looking at different pinball stores I can see online the two motors needed (24V, and 5 VDC), but there are two pieces impossible to find, from the manual these parts are: motor cam assy 515-5814-00 and the crank arm 535-6657-00, there is also a spring that I can see in different pics in the internet which is at the end of the crank arm, but is not showed in the manual, so my question is if someone could have those parts available for sell or if anyone has a detailed drawing of those parts showing dimensions which allow me to re-do it.
Many thanks!
