I need help with the reverse lights.

I know this is an old post but here is some additional info...

The part number 2883 211 is good for searching. Hilltop Auto Parts has some (as of 9/2019 buy they are pricey)

The small dia pin that sticks up on the black one (newer) is a pin that gets pressed in to lock the post to the shaft (other posts have said to cut it off, DON'T DO THAT)

Take care

Dana
