I agree with one bad snake. I watched the "Wizard" Chuck Tator change mine out. It does require removing the rivits in the trunk and breaking the glued seal on the front of the trunk wall. You also have to remove the fender well lining on the passenger side rear wheel, this also requires drilling out the rivits on the edge of the fender well, must be very careful as this is right up against the body and one slip could equal a scratch. You have to remove this to disconnect the fill tube or fill hose from the gas tank. Then hope and pray that when Dodge put your body on, obviously after the tank was in the frame, that none of the body resin or glue they use to mold the body leaked onto the tank. Mine was basically glued or molded to the car. It can be done but be ready for a few hours worth of work. Also dont forget to get all the rivets and a heavy duty rivet gun.
Like mentioned earlier I would suggest taking it to the dealer, as I think it is only booked at 1.5 hours. Or if you do it yourself call Chuck Tator at Tators Dodge to get advice and the proper rivets to put the front trunk wall and rear fender well back in.
