This gives you access to the two bolts holding the upper control arm onto the chassis.
I removed the ABS sensor wire bracket from the control arm then took my breaker bar to them and they came out without any trouble, so I now had the steering knuckle out albeit still attached to the upper control arm plus a massive void in my wheel arch
A nice whack with a mallet and the upper ball joint came out the knuckle
here you can see how much I mullered the ball joint thread using a ball joint tool 
The tool wasn't deep enough to be centred on the thread and bent it... Oh well, could be worse I guess!
I'm dropping the knuckle off along with a new ball joint at my mate's garage tomorrow, so they'll get that swapped out for me sometime this week. I've found a whole new upper control arm for £35, so will be ordering that as it'll probably work out cheaper than a replacement ball joint and labour (even at mates rates!). Hopefully start putting it together shortly
Other main thing on the list is sorting out a passenger side engine mount, as the engine has sagged enough to damage the front mount now
will be getting the stud from a Prelude side mount as a temporary measure, but will have to look at getting a custom mount fabbed up soon! After that it's bolting up the ancillaries then sorting out the wiring loom. Gradually getting there!
