    I've read about installations of the "large" 31-ish gallon 2nd generation Blazer gas tank in a first generation and how they require relocating a crossmember and they reduce clearance.

    How about the "small" 25-ish gallon second generation gas tank? Has anyone put one of these into a first generation? Do they require crossmember relocation and/or reduce clearance?

    Do the 2nd generation factory skidplates work on the 1st generations?

    I want extra gas capacity cheaply (so the nice Aero and NWMP tanks are not an option).

    i dont see why a newer one wouldnt go under a first gen, as long as fuel filler diameter is same for hose and if you have later straps and all then i dunno why wouldnt. i know an 86 blazer tank pops rihght in under a 67-72 pickup anyways and the only real difference from pickup to blazer frames is the rear drop down of frame rails for the rear bumper
