60 Series Power Steering!
I bought the 60 series power steering from a friend named Brett, he also does rear disc brake conversions, disc brake handbrake conversions and 60 series power steering setups for right hand drive 40series vehicles.

The kits are professionally do not look out of place on the vehicle, so even if you can't or don't feel like getting approval no-one will notice it anyway!

Just as a preliminary, You need to get a 60 series steering box, and some other 60 and 75 series parts, it will probably cost a total of $500-$600 dollars, and make sure you get DOT approval and use the bolts etc relevant to your countries regulations, playing with your steering is playing with your life!!

Okies its a lotta work, but a direct rod runs from the firewall to the steering box, which will then be located on the front of the vehicle, which, obviously then steers the wheels, (similar to the saginaw setup in the states) but almost exactly the same as  a standard 60 series setup. Pay careful attention to legalities in your area, but this mod is very worthwhile, especially if larger tyres are considered in the long run.

I have noticed vastly improved handling, but I also rebuilt the whole front end while i was at it, tie-rods, bearings, seals, etc. (This is not a fun job!)

One last problem you may have is the compatability of your engine for a power steering pump. I have a Turbo Landcruiser 3B, 3.4 litre 4 cylinder diesel.
My turbo is located very high, keeps it out of the water and stuff but it also is where a standard pump bolts to the engine, but I couldnt get any f the pulleys or anything anyway, so I had to make a bracket and bolt my pump to the a/c location, and have an almost square belt setup. The only problem with this is that it doesnt leave a lot of room for adjustment!


HOME!
With the radiator, front guards and drivers side tyre removed. You can see the 60 series steering is on the left, and you can just see that we had to chop a fair bit out of the shock tower to get it to fit properly.

I mounted a remote reservoir, for the power steering fluid. I put this on a bracket next to the brake master cylinder in the top left of this photo, that part was simple. I put the pump on the bottom of the engine where the air conditioning compressor would go.
I also had to grind the rivets off the shock tower and botl the shock tower on a little further back. I then flipped the shock holding bolt around inside the tower so it faced the other way and when this lined up, i bolted it on. Then I carefully measured all teh bolt holes and drilled the power steering box, and then marked out a portion of the shock tower that i wanted to remove and did that. Then i bolted everything in and put some crush tubes, on the bolts that were going through the chassis, so it didnt crush and used some big washers.
