Does anyone know how to remove the seat cushion from the seat pan of a standard seat. I am trying to install the oem fire extinguisher kit from Suncoast. The bracket has backing plates that need to be between the seat cushion and the seat pan. Removing the seat cushion seems like the only reasonable way to do it. I even took the seat out of the car today but could not figure out how to remove the cushion. I also wanted to go for a drive so I put the seat right back in.
