Re: 80 Bronco???
For some quick info, check out: off-road.com/ford/bigbroncos/faq.html on this website. Probably want to read it from the beginning through '80.
I'm sure others can comment with more knowledge on this... I remember hearing here on this BB that in '80 Ford experimented with a lighter-duty frame, that it was not a good idea, and they went back to a more solid frame. Don't know if '81 was back to solid, or if it wasn't till '82.
Can anybody help out on this?
