DEALER INSTALLED ANCHOR CHILD SEAT WITH TOP STRAP
Model and Year 1984 110 AND 125 INCH WHEELBASE "G" VANS, EL CAMINO, "S/T" PICK-UPS, EXTENDED CABS, BLAZERS, AND "C-K" TRUCKS
NOTICE: All hardware discussed in this bulletin should be supplied or available from the child seat manufacturer. Be sure the child seat position does not conflict with any additional requirements provided by its manufacturer, or with any recommendations in the Child Restraint section of the Owner's Manual.
The child seat may be used only in a forward facing seating location. However, installation is not recommended in the front passenger seat of "G" vans. The second seat offset to allow passenger entry does not position a second seat lap belt within the recommended zone for attachment to the top strap hook. Moreover, a floor anchorage is impractical since the top strap length is insufficient to directly connect the restraint to the floor with high back bucket seats.

Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition.
