    I just did this a few weeks ago. you will need
    73-87 blazer 31 gal tank
    skid plate
    gastank straps
    1-3/4" to 2" adapter pipe

    you will have to remove your rear xmember, i would recomend taking out the rear bumper and hitch if you have one. the hitch may not fit back on. you will also need to move the brake line braket.

    I used 2 1/4" 2x2 by 34" angles to hold the tank up. the straps run from front to back. I have some pics but have not developed the roll yet. It will be another week or so before i post some pics.

    The tank will hang down about 2" lower unless you have a body lift(I have a 2" body lift)

    if you have more questions PM or email me.
