you sure?
ashcrofts have a diff diff (?!) for P38's - but they do mentiion 2 pin and 4 pin - not the ratios.
according to Ashcrofts - the only diff seems to be that the P38 rear has a 4 pin diff - but that is interchangeable with the front (2 pin) to give added strength. There is no other comment - ratios, long noses etc.

All P38A differentials are the same apart from the ones fitted into the rear of the 4.6HSE. These incorporate the 4 pin diff. All the others have the 2 pin diff.
what size tyres do you have ? fitting something like some 750s helps on a series

according to that link, Trewy - thay are saying that the same diff was fitted to ALL vehicles both leaf and coil until 1993 - then they changed - and yes - the Wolf and the P38 4 pin are the same.
