    <font color="blue">Yeah but you gotta make new crossmembers to put in the frame because the later gas tanks are suported in the front and back instead of the sides like ours. I have a 87 31 gal tank in mine and I used 3" angle iron to make the new crossmembers out of.

    And the filler neck faces the wrong way too /forums/images/graemlins/tongue.gif

    <font color="blue">Mounting it backwards will put the filler neck on the right side, but the tank angles up in the rear so if you turn it around it sticks out further. Some of us need all the departure angle we can get, rocks already decreased my capacity and it's only been in there 8 months. After I hammer it back out, I need to build a thick skidplate /forums/images/graemlins/1zhelp.gif or mabye go down to a 25 gallon
