Replaced the door jamb switch with these guys from Rockauto. I think they were about $1.00 a piece. They fit well, and screw in nicely but there's a little wiggle in them. I would have preferred a more firm screw down. I'm going to add a washer to see if that helps.
Also on a side note, there is enough thread for you to adjust these to your door and door jamb make up. I would image all are similar but just in case, you can just barely screw it in for a long switch striker or screw it all the way down to push the striker further from the door.
