M16 x 1.5 pitch from what I wrote down when I was changing the reservoir and cooler on low pressure side:

Have recently finalised my power steering stuff, so its fresh in my mind.
1) mounting behind the turret is a squeeze. It doesn't allow for easy removal if required, and you have to lengthen/shorten hoses as required.
2) you need to use hydraulic or ptfe hose as the power steering fluid will slowly eat through standard rubber hose and weep/seep/fail. Fluid will go black as PS fluid eats through hose.
Low pressure side
Power steering rack barb outlet = 3/8ths ~10mm,
Power steering rack fitting is M16x1.5
Power steering pump inlet = 5/8ths ~ 16mm
Reservoir inlet from cooler = 3/8ths
Reservoir outlet to pump = 5/8ths
Cooler inlet / outlet = don't know as I went aftermarket, but if someone knows then I'll update this list.
High Pressure side
Keep the factory stuff. You gain nothing except an emptier wallet trying to change OEM crimped hose with fittings pressure rated correctly.
To replace, you'd ideally get professionals to crimp 1000psi rated ptfe/hydraulic hose from pump to rack.
If you are going aftermarket cooler, get one with 6AN fittings on it, otherwise you have to muck around with 10AN to 6AN reducers which is a pain.
If you are moving the reservoir to around the headlight area
a) you'll have to find a mounting point to mount reservoir. Bracket is made for above the wheel arch, so you'll have to retrofit something to mount it
b) you'll have to extend the reservoir outlet/pump inlet hose (5/8ths) to the reservoir
c) you'll have to shorten the reservoir inlet hose/cooler outlet hose (3/8ths) back into the reservoir. Can't remember if its mostly hard lines back into the reservoir, but my st185 has hard lines quite close to the reservoir.
You can extend the reservoir inlet hose and loop back to the reservoir if you wish to retain hard lines.
Not sure how accessible parts are in the UK, but I popped down to my specialty car parts store (note - NOT big brand - they are generally muppets) and purchased my 3/8 PS hose for cheap.
For the larger 5/8th hose, I had to source the hydraulic hose from a specialty hose business which does industrial stuff as the car parts store wouldn't indent 15m so I could have 1m haha.
I'm using p-clips to hold it all in place and I made a mount to relocate my reservoir to a better position (although I'm aftermarket PS reservoir, same logic would apply in relocating).
Figure out your reservoir location and mounting, figure out how you will route your piping - measure thrice or more (then buy extra to ensure you aren't short when you put it all in), figure out if you will replace all fittings or just use what you have, figure out if you will move to aftermarket PS cooler now and then figure out the previous steps again
Have fun
