Well you've got your answer, but if you come across another Ford you don't have the codes for here is a way. I might be wrong on newer trucks, but for many years Ford had ID tags on a bolt for the diff cover. One might say "75W-140 SYN ONLY" and the other would have various information on two lines(model, build date, etc.), if you look at the bottom line, left most numbers is would give the gear ratio and limited slip or not. EX:
  • 3 73 = 3.73 open carrier
  • 3L73 = 3.73 limited slip
