    Ok, always like to plan ahead, i mean for cryin out loud havent even got my engine or body lift on yet and im thinkin about the axle swap ill eventually do. Anyway, just wondering, when i change from my 14SF to my 14FF (88 2wd 'burban vintage) will i need to change driveshafts? I think that the 14ff is longer than the 14sf, but since i already have a 4" lift i was wondering if it would sort of balance each other out. Also, will the 14ff give any kind of height advantage over the 14sf? thanks. k20.
