I`ve just bought an LSD from a Monza
The guy said ..................
These should fit, omega a/b,
so really the full range of: senator/monza from 1978 right up to the 2003 omega b!!
i think they will also fit the rekord estate also maybe others.
but then those in the know WILL KNOW........
just counted the teeth...
11 on the pinion and 38 on the crownwheel
i make that 3.45:1 ratio
That ratio is spot on too, all I have to do now, is build it in the Omega diff casing
