Click to view attachmentClick to view attachmentI am putting my car back together after paint and I have a small rectangular piece with a machined 10mm hex bolt in one side.this is the early car window set-up.I will try to send a pic but I don't know how to size them.PH1( Kelvin) is going to stop by soon and help me get that together but for now.
Where does it go?

Goes in the slot for the front vent window. Look at the rubber for the window and you will see the slot for the piece. Not used on cars after 72/73.

Thanks Mark! I will go take a look.
