might be too much work, but if you want to keep everything super hidden to keep that bare bones board tracker feel, i got a doozy for ya. im warning you, might take a lot of fab work.
here it goes.
since you need a something to mount the top motor mount to, put a piece of that frame tubing on level with the bottom of the tanks, then cut the inside off one of them, and then weld tabs (with nuts welded onto on the backsides of said tabs) onto the inside. you want them level, so that when you go and screw (countersunk) the side back on, its all flush. solid mount the side of the tank to that tube i mentioned earlier and to the underside of the backbone. so that the flat part of the tank will be flush with the backbone and motor mount, and it should look like this, (see pic below). now in order to get at the electronics, youll have to take off the other gas tank, and un screw the screws, and since it screws INTO the tank, the tank comes off, and the electronics stap in place
o yeah, and run internal wiring. you can start the applause now lol
red is new tubing, and black is the motor mount
dots are countersunk screws, and the L shapes are where it wounts to the backbone and top mount for the motor.
im a fabricator, not an artist/photobucket wizard. so dont hate the crude drawings.
