LT77 tunnel clearance with R380

Can anyone help confirm if the tunnel from a 200tdi will fit over a 300tdi R380?

I plan to mount the R380 on the LT77 mounts so I can keep the original seatbox, but will the bulkhead tunnel clear the 300tdi bell housing??

You may have to use a bulkhead diaphragm

Given that the LT77 and R380 are basically the same gearbox there shouldn't be any problems It is not a Defender, it is a One_Ten

The bell housing of the 300 tdi r380 is considerably larger than that of the lt77. Is this why the tunnel size was increased?

Whilst the gearbox remained in the same location, when the 300 was introduced the engine was moved forward 8 inches, hence the longer bell housing. Plus the R380 has a longer input shaft.
There is a short bell housing available for the R380 to enable its fitment with alternative diesel engines, presumably with a shorter input shaft It is not a Defender, it is a One_Ten
