The V5 and 6 box will start TY754 and if you look along the casing you will see all the bolt lengths are the same and in line.
Ver 1-4 boxes will start TY752. Bolt lengths vary and are not in line.
I think the TY754 casing is stronger.
The ratios vary from model to model. The tallest 5th in a classic will be .728. There is a .825 which is quite short and there is probably an even shorter .9 something V ltd.
These ratios are common to 752 and 754 casings.
Diffs vary model to model Jap/European.
European boxes are 1.1:1 transfer gear with a 3.9 front diff and 3.545 rear. Both 752 and 754.
Jap boxes are 1.0:1 transfer with, usually 4.11 or 4.44 diffs. Both 752 and 754 boxes.

Thanks for information, but at the jap versions: do you mean it is a 4.44 diff rear and 4.1 in front or do they all have 3.9 in front?
What would be the gearratio if there is a 4.44 ratio rear diff fitted? I think very short isn“t it?
