Get straight into the restoration. Don't worry about fixing the game now, as all the faults will be addressed during the restoration process. Take your time and enjoy the process. Male a list of the parts you need as you go along. There's nothing worse than placing an order and then realizing you forgot something !

This is a bit of the opposite of how I do it presently. I like to get everything working first, so you aren't questioning your restoration work if something doesn't work once the pin is put back together.

I've done it both ways, it works both ways, but I thought I'd share an alternate theory for consideration.
