Can anyone supply me with a dashboard ash tray, in either black or
brown, cheap?

I don't care about the condition of the inside as I will be cutting the
bottom and the front (that you don't see when it's installed) out of it.
  I'm going to install some gauges in my dash mounted console and I want
the ash tray just for it's ability to cover the hole at the top.

The gauges will be right in front of where the ash tray would normally be.

The console is the type sold by EuroCampers or BusDepot
