So ventured out and got the wishbones back on today with new polybushes. Bit of a faff getting the arm in at first. Realised I had to take off the roll bar link pin on both side and push the bar up out the way. Luckily the links came off easlil as I think they've been replaced recently so were seized up.
The other bits that were a pain were relocating the nut back in the subframe for back bolt. Passenger side seems more confined to get at. After tightening up the bolt, the socket seemed to get stuck on the nut in the subframe and I couldn't get it off for a while. Luckily there is an access hole in the side of subframe I could see the socket through so whacked it a few times with a screwdriver hammer combo and it loosened it off the nut enough for me to "octupus" my arm in and round the sub to lift it out.
Next bit giving me grief was getting the ball joint back in under the steering knuckle. I utilised the strong bar through the hole in the arm and levered it down as far as I could until it hit out on the subframe.
At this point there seemed to be still a couple of mils still to go but putting the balljoint stub at an angle was just enough to catch under the end of the knuckle with some brute force pushing down on leverage bar for the wishbone. I then had to quite violently shove the knuckle forward so it popped into place. This has to be done with the steering in straight ahead position. It won't work at an angle.
When I was putting the WB back in I devised a way to hold the strut back out of the way so I could feed in the WB easily. As you can see from the pic below I put a strong bar in between the brake caliper bolts, shoved it back out the way and then held strong bar in place with the side of my leg. P.S, this only works if you have thighs that will crack walnuts!

Now from looking at the wheels they do appear to be a little less tilted in at the top although measuring with the spirit level and gap difference between top and bottom of wheel still seems much the same. I didn't think the bushes would make much difference here as it looks like the camber does need significant mechanical adjustment still.
Yes will be getting another pair of work trousers soon

While I had it up on stilts also cleaned off the sump of oil and around that area. Had a look at the exhaust as well as it is blowing forom back end and the front sections look well past it too. Looks like will need a whole new system in the not too distant. Back section has been extensively cowboyed up with some sort of metal wire and exhaust repair tape or whatever it is.
