TO INSTALL VENT WINDOW SEALS IN A C BODY COUPE AND OTHERS
Put the seal in the channel where the pivot pin goes through.
Put the short end of the seal in place.
Put the longer end of the seal in place.
In between the pivot pin and the long end, the seal will be bowed out away from the channel
(due to it appearing to be too long) Work these bowed out sections of the seals into the channel and you're done.
