I have bought a disco that has had a heavy O/S front impact and it had shoved the axle back a bit.
The resulting backwards shove of the axle has pushed the prop back and it has alsp pushed the transfer box back and it has snapped off 2 of the mounting hole lugs on the back of the LT77 box as circled in the picture. (picture is a library picture and not my gearbox)

The gearbox is a genuine land rover replacement item with the land rover approved replacement item id tag on the bellhousing and is in very new looking condition so hence i think it may be worth repairing.
Can anyone confirm if the silver rearmost casting on the above picture is available as a spare part, and how big a job is it to swap that bit of casting.
Oh by the way the only gearbox i have ever peered inside was a ford type 9, and all i did was peer inside and quickly close the top and say ' well that looks complicated in there!'
Thanks
Colin
