i will probibly go with that for now and upgrade to this later:
I'm not sure I'd call moving the tank an "upgrade". I personally drive a '66 and a '65 both with the tanks behind the seat - where they were meant to be. I don't smell gas (not even on hot days here in sunny FL) and there is no sloshing noise. And I don't have to worry about moving things around in my beds when I have to fill up with gas. Just my 2 cents worth.
