could someone tell me through what years are which generation bronco?
im new to the bronco but i really like it. i just got an 88 full size bronco w/a 351w, 4wheeldrive and im ready to start workin on it. i would like to know if i could swap frontends, like from the 88 to a 91 or so.because i think they are diff. right? but would the 91 front just bolt right up to mine?(grill, headlights cosmetic stuff, like that) and why does my speedo read 180mph? kinda crazy i thought. also, where is the best (cheapest) place to but stuff to lift it. maybe you could me what i need to but to lift it? like i said im new to this stuff. i was into drag racing (still am, but i wanna go offroadin too.)
well please help if you can.

thanks, josh from ohio
