Hi there thunder92,
I have a 96 and it has 3 brackets, just in front of the upper tailgate. I always wondered what they were for 'till Mrs Boss way babysitting a friend's kidlet.
Mrs Boss installed the kidlet seat and threw over a long flat tape, with a clip on the end and asked me to "clip it on and tighten it"!
Evidently, Mrs Boss was a nanny for a few years and had all sorts of cars to drive, so she's the resident expert in kidlet safety gear :clap:
Hope this helps,
Cheers,
Mick.
