Should a customer request the installation of a child seat top tether anchor, in their 1984 Corvette, the following installation steps are to be performed:

  1. Remove rear floor carpet and insulator.
  2. Drill a 9mm (11/32 inch) diameter hole through the front at the location shown in Figure #1.  CAUTION:   Double check hole location to avoid damage to the vehicle under-carriage components.
  3. Reinstall insulator, cut 38mm (1 1/2 inch) diameter hole for washer/spacer*.  Reinstall the carpet and cut a 9mm (11/32 inch) diameter hole for the anchor attachment bolt.
  4. Using a suitable sealer, such as silicone or butyl type caulking, apply a bead of sealant around the 9mm (11/32 inch) drilled hole in the floor pan.  NOTICE:   The sealant is to be applied on the outer side of the floor pan (see Figure #2).
  5. Install the tether anchor bracket, as shown in Figure #2, and tighten nut securely.  NOTICE:   In the event the tether anchor assembly is removed, the 9mm diameter hole must be properly resealed to prevent exhaust fumes from entering the vehicle.

Three (3) flat washers 32 mm (1 1/4 inch) x 3mm (1/8 inch) thick, with a 9mm (11/32 inch) diameter hole.  Total stack-up of washer/spacer is to be 9.5mm (3/8 inch).
