75 3.0 has a 3.3 LSD
75 2.0 Nord has 4.3 non-LSD
75 2.0 TS has 4.1 LSD
75 1.6 has 4.55 non-LSD
75 1.8T has 3.9 LSD
75 1.8 I don't remember

Then there are a bunch of Giulietta models, the one you need to know about is the 1.3 that has a 4.78 non-LSD.

Some adds to the previous.
75 2.0 Carb - 4.1 open.
75 TS - 4.1 LSD
75 1.6 - 4.56 Open
75 1.8 T - 3.91 LSD
Giulietta 1.3 - 4.78 open
4.3 open was in some 1.8 models. Problably Giulietta and 75

MZ beat me to writing. But I'm sure the 75 Nord is 4.1 over here at least.
The 75 3.0 must be available with 2 different ratios. 3.55 and 3.35
And our round/trunc function differs slightly

And our round/trunc function differs slightly

Agreed, but it's really semantics.
