Not sure if (by project) you mean you are restoring a game or building a custom game from scratch.
The interconnect board is unique for each game title it went into (20 different variations), so if you are restoring a game, it'd be helpful to state which game it is so you get the correct one and not one for a different game that you'd have to replace resistors and connectors on.
If you are building a custom game, you may end up having to hack one apart anyway. One option for you to consider (if you are going custom) is that GLM can build you a custom one that would make it easy for you to configure to your end application. Plus it is WAY easier to install and remove than the factory board (something you may have to do if you are building a custom game!).
Hope that helps, and good luck!
