I read thru the bible and in one part it says NT are all 3.9 but the other says that 1.3 is 3.7??

So which Ratio is the 1985 SWB NT Diff & 1.3motor???

1.3 NT = 3.9:1 diffs.
1.0 = 4.11:1
WT = 3.7:1.
Of course there are oddballs like Maruti to stuff this up.

Its easy to tell...
Stop one axle from turning and mark the other drum and backing plate... turn the pinion and count the turns it takes to get the drum to return to the mark.
