Hi Mowerman, I have a LH118 with a lot of your list done.
LH119 is 2.8 liter diesel (engine code 3L)
The snorkel you can buy with the part number, but please note that it makes extra noise (only solvable by adding a turbo
)
Which set of wheels with tyre size? I have 225/75R16 on Landcruiser 60 steel rims (ET0 or so) and that only fit with modifications to front wheel arch, because otherwise you can't steer.
I'm also not a huge fan of the spare wheel carrier on the rear body, IF you are going to putt on a heavy full size spare of a bigger tyre size with a steel rim. That is much heavier. Not a problem for a campervan which does only some holidays but with a lot of driving the load on the sheet material may be too much.
I have a rear bumper on the tow bar/hitch frame, which comes with a swing out tyre carriers, but that is all custom made.
But with all the modifications, it is as capable as an unmodified Defender or Landcruiser. Usually a bit slower, but it really goes anywhere.
Mine even came with a factory LSD.
Bullbar will have to be attached to the chassis-like beams running behind the front bumper. Again a bit custom work.
You can checkout the side of Hiacehobo, he also has a LH119 with same modifications. I based my modifications partly on the info on his site.
