I'm looking at pulling a luggage rack at a local yard. It appears there's a thin metal "U" shape cap that snaps over the base part of the spear. Is it just a matter of working a thin blade into the end of the "U" and gently working one side out of the groove that retains it?
I also spotted a notchback at the same yard with an IMSA type spoiler on the back. It's split at the top edge at one end. I don't know if it's worth pursuing as new ones are available. If anyone's interested its at
