wizard:
yes you will. And the hand brake cable.
If the speedo is of the electric type on the r380 take the mechanical speedo drive off the LT77 box and fit it to the R380 box.

wizard :twisted:

Range Rover Blues:
R380 will bolt in in place of the LT77.  Both fit either the LT230 or Borg-Warner T-box.

Later models have differnet crossmembers, though I've seen 2 types on V8s with LT77, it's more to do with exhausts than gearboxs, the 3.9 had a bigger pipe than the 3.5 and later cars with R380s also had catalysts.

The early 3.5 crossmember should fit fine if you have that.

les baty:
i swapped my busted r380 for a low mileage lt77 without any problems, the only difference is where reverse is, altho i think the r380 is a better gearbox........ps its a 300tdi disco

crazymac:
After buying mine I realised it had been fitted with an R380 (its a 1991 J plate Disco) As far as I can see the only thing is the length of the bellhousing?
