I ve got a 70 model and need a fuel tank. I read the fuel tank upgrade but it says 71-something, what to do about my 70. that mustang tank sure looks a lot like mine.
The Mustang tank is wider and not as long as the Maverick tank. It takes some fabrication skills to adapt it to a 70. Your best bet would be to take yours and send it out to be refurbished.
or... ...or run a fuel cell. girls will think your much cooler if you have a fuel cell. (my wife is punching me in the spine RIGHT this second as she reads...)
