    Can be done Mike Steele at Innaminka did it back in the 1970s.
    You would want to be careful though the gearbox and Rover rear diff (if it doesnt have a Salisbury) wont be happy
    Cant help with adapter info though

    Hey lostkiwi, do you have to worry about engineering / rego on the island ? Would imagine you'd have a certain amout of freedom and leeway with that sort of stuff.

    they do have molds /patterns for a v6 to a series box - it was a custom commision some time ago. You'd have to ask around at crs but someone there will know where its hiding.

    Have you thought about going 253 to a toploader and adapting that to a series transfer case?

    or a mild 202 will match a 253 for torque and oomph.

    Back in 1976 I made one up myself.

    Took a drawing off the back of the engine and the same off the gearbox bell-housing and had those profile cut. Did all the calculations then had a spacer piece cut out of a metal pipe (but today I would have it rolled from flat bar) this was then welded; surfaced to be true and parrallel; then drilled and tapped those that needed it.

    I used a Borg & Beck 10" clutch pressure plate from a Rover 3 litre and it's corresponding friction plate. (The B&B pressure plate is an exact match for the Holden flywheel.) From memory I also had to have a boss machined to fit the back of the crankshaft and support the pinion bush for the Land Rover.

    Mine was a 6 cyl chassis, so the rear 4 spark plugs needed to be accessed via holes in the firewall inside the cab with rubber plugs that used to cover the side of the gearbox cover on earlier models. To clear the width of the engine, I also had to widen the profile of the engine bulge in the firewall, this required a bit of cutting and shutting, with the second vehicle having the firewall removed to do the job more professionally. The LH exhaust pipe was a problem going over the starter motor, very close to the chassis and the corresponding heat it brought onto the passengers feet.

    If I did it today, I'd use an LT95 box with an overdrive or 3.54:1 diffs and the front end out of a stage 1. I would also bring the engine forward to be closer to the radiator and allow room at the rear of the engine for the exhaust and access to the spark plugs.

    Geez I loved the get up and go that car had. (I subsequently transferred it into a Station Wagon)

    Addit: I actually ran Rover Car diffs with a Fairey O/D (I seem to remember they were the 3.9:1 ratio from the P5, but may have been the P4 4.3:1) and in fact when I changed the cars over I had to sacrifice the Suffix H Salisbury because it was the only way I could keep the Rover car ratios.

    You won't find me on: faceplant; Scipe; Infragam; LumpedIn; ShapCnat or Twitting. I'm just not that interesting.

    Hey all
    Thanks so far
    Hardchina one good thing about Norfolk Island is you can pretty much do what you like as long as the doors not falling off lights work etc!
    Still have to get a Rego. $130au a year or half that, if it's over 30 years old
    Looks like i might have to go to plan F. Thats find an adaptor for a 4 speed Hilux box .Or just go back to plan C which is go with the 250 Falcon I have already have with adaptor.
    Still can't beat the sound of the V8!

    I bought a 253 with an adapter to fit a 4 cyl gearbox in the late 80s. I sold the 253 to a guy with an HQ ute and can't remember if he returned the adapter. I'll have a look in the garage when I have a spare moment.
