Hello, Along with fitting a 200tdi recently to my '85 model 90 , I also had a transfer box change.
Currently running a 43D (exTD5) with 1.410 ratio
To me it seems to be geared wrong ,and I feel engine is very revvy and really is only good for about 60mph, above this it just isn't comfortable
This is fine tootling around the local lanes but it makes for noisy and not entirely comfortable driving on motorway

Any advice as to a more suitable box /ratio ?

Rod,

Try an LT230 from a Disco 1, I think those are 1.2?

My 110 has a 1.4 and above 65 mph I start to hit that wall... but my disco will hit 80mph.
