Rover V8 Gearbox Question

[spinningfish]

Hello all

I'm going to be putting an R380 gearbox, out of an LDV Pilot van, into my V8 P6.

I've got two questions in respect of this. Will an SD1 LT77 bellhousing fit to the R380 'box? If so, will the gearbox mounted to the engine be the same length as an equivalent LT77 setup?

Many thanks
