    whats special about 89-91 K5\'s?

    what are the changes from 88 to 89? do the 89-91's have a different FI setup? and are they desirable? how are codes retrieved for the 88-91's?

    any other body, suspension, etc differences appreciated too. /forums/images/graemlins/smile.gif

    the 10 bolts in the newer ones are 30 spline I believe. I guess its stronger, but its still a weak 10 bolt. The front suspension's shackles are longer to prevent spring to frame contact. They have the nice looking grille setups. No fuel injection change. As for reading codes, just stick a paper clip in the diagnostic ports and read the codes by the flashing of the Check Engine Light.

    89-91's have the cool front clips(4 small headlamps side by side) and they have the NP241 with electric speedo, also I believe power mirrors started in '89, could've been '90 though. That's as much as I know. /forums/images/graemlins/dunno.gif

    My '91 has a better armrest design for the rear seats and better designed sunvisors up front that don't hit the mirror everytime I use them.
    It also has a better radio that is easier to replace with an aftermarket.
    Oh, and a little light in the engine compartment on a reel.

    Basically I bought it for the front clip and all the little details were gravy! /forums/images/graemlins/grin.gif

    what? never heard of this. 350,305,4.3 V6s all use the same throttle body. 1 7/8" bored unit. 454s use 2" bored units, and besides TPS and vaccum ports I've never seen a difference.

    My 91 has armrests in the rear but I think they are kind of cheesy. They're basically just big pads velcro'd on the wheel well hump.

    These years also offered rear ABS brakes.

    I don't think those are standard, my 3rd row seat has the arm rests built right on it, so was a friend of mines '91 2wd Burb.
