Overdrive parts availabiliy

[junkyardjeff]

I have a 65 Mercury Montclair with a 3 speed o/d that does not work,it had burnt wires so they been repaired but still no o/d. Been running tests and relay is good but even with both wires to the solenoid disconnected and the relay grounded when the blue wire is hooked up to the solenoid it wants to arc and no click so I think I need another solenoid and is there anyone who has any or rebuilds them.
