HI, I've had a Sophia from 1969 since around 1970. It's got a metal Ginza upgrade kit on it, but I've lost the tray. Not too worried about that, as I can probably make a new one out of fiberglass or plastic that would work.
I could make the part below probably, too, if I had dimensions, but I want to see if anyone's got a machine they can sell me that has one on it, or can just sell me the part. Here's a pic of a machine similar to mine with the part I need:

The part I need is the blue drop-through above the lower tulip that's just above the drain.

If anyone could help me find one or make one, that'd be great. The hole is drilled at such an angle that it looks like it was fed from behind, because the ball would have to travel uphill to drain properly. This one's hole was blocked off by a tab, but I've removed that tab. A simple win pot won't work unless I redrill the hole.

Also, I'm looking for about 2000 pachinko balls. Everyone's sold out. Is that going to last a while?
I will post a pic of my machine when I get home.
