Coin mechanisms and coin circuits
Coin mechs (acceptors) snap into the coin door hardware without wiring; the hardware bolted to the door is permanent. Styles differ, so make sure a replacement mech fits your door. One working mech is enough. Coin circuits are the most neglected part of most games, so expect severed wiring and damaged or absent parts there.
