I did mine a few years ago. I got my panels from someone I won't recommend, finally did get my pieces but it was more effort to get them from my vendor than I had anticipated. That said the work on the helm area panels is not hard by any stretch and really improves the look without many dollars or effort. When I redid mine I went with Smartcraft analog look engine gauges with two Smartcraft monitors for a sort of retro look. I would have liked to put in a multi function display in the gauge panel but there really was not enough space so I went retro instead.
Good luck with your project, nice to see people caring for the Classics.
