How many small metal inserts (small tubes where the 4 mounting screws go through) are there in the wiper/turn signal switch? I only have 2, should there be 4?

I seem to remember 4.

Each screw should have a tube to prevent distorting the switch body when the screws are tightened down. So 4 tubes are needed.

Thanks for the replies.

And don't get ham fisted and over tighten them.

Think of the screws as holding the switch in place but not pulling it down into place.
