Bit of an update,
Finally got the steering (power) set up, ended up using the Mazda T4000/ Ford Trader unit power steering box, mounting brackets and adjustable column.
lot of ginning around modifying the mounting brackets, chasing up the correct power steering hose ends to fit the Range Rover pump, lots of foul language and tearing of what little hair I have left.
Looks like stopped all the leaks, with engine at idle turns lock to lock very easy, going to try and refurbish the original steering wheel, needs a converter boss turned up in a lathe. Not really worried as also have a SAAS fine spline boss that fits the Mazda column, may even go down a size or two in overall steering wheel diameter, original is 18 inch with Armstrong steering, plenty of after market 15 0r 16, even 17 inch wheels around.
Dunno if you can make out the dash, has been heavily modified to take all the gauges and switches, will feed all wiring into a couple of 10 or 12 pin quick connector blocks, got plenty of room and make life a bit easier if and when the shed comes back off again (rust repair and painting).
Progress has been a bit slow, but you know what happens if you rush things!
