With the output flange having 3 legs and 3 bolts...could easily have rigged up a sensor to read those.
You could, but are the number of pulses per prop revolution correct for your speedo head? You can convert electronically, but making a toothed wheel with the correct number of teeth seems a much more sanitary way to me.

Interesting, what is the weight like vs the LT77?

So the Getrag GS6-37 box has a torque rating of 370Nm?
The R380 fitted to the Sherpa is rated at 380Nm, and compares in weight and size to the LT77.
The 2wd versions are scarce, though.
We had V8 Sherpas at work, back in the day. And the ratios seemed wider than the car version?

Piece of piss for a pulse converter and easier.

I have never even seen a 2wd version, so I can't speak for the ratio spread, but there was a bloke on the Rover Forum who fitted one to a P6 and he was happy with it.

There were two versions of the 2wd of R380; the van (Sherpa) and sports car (Morgan/MG) with the Sherpa version having very low first ratio.

Yes, commercial boxes have 4.1 or something first gear, also 2nd and 3rd ratios are a bit different.

My R380 box came from commercial vehicle and I had to rebuild it with passenger car gears. I got all I needed from Ashcroft. By the way, input shaft is also longer on commercial R380 boxes.
