I've got an '87 110 CSW with the absolutely pants 2.5 petrol motor. I'll be grafting in my 200tdi disco motor shortly. The disco was on an LT77 box will it be an LT77 in the defender?

I know the transfer boxes are different ratios but is the box geared the same?

Cheers,
Paddy

Yes it will be the lt77 but short bell housing rather than long that was in the disco
