Actually, they are technically called power outlets unless the car was purchased with the "Smoker's Package" which came with a removable ashtray that sits in a cup holder.
Honestly, I just keep a collection of BICs in the center console, and use the outlets to power misc. stuff.
The answer to yer question is yes, you should be able to find one in the junkyard in a wrecked PT fairly easily. Just pay attention to where you pull the wires from so you can duplicate it in the new one.
