Passenger side was where I started out.
The bolt was top down through subframe hence bolt head in subframe comment, so I could crack the nut on the bottom but as soon as it loosened the whole thing spun, therefore had to secure from top. I thought maybe could get an extension onto the socket as I could get that in onto the bolt head. Ended up with a 1/2" flexi joint then a small solid extension then ratchet sitting just above the steering thingymabob.
Drivers side was actually a little more difficult as the idler arm was in the way and could see the starter wire at close range

Other than that everything was well easy to remove. Glad the balljoint had the pinch head rather than the top end nut. Just split it with chisel - which is a bit of a pita when it firms itself into the slit, there is hardly any room to hit it due to roll bar in the way.
So I have all the bushes removed except the collar of the larger front bush so will need to cut that off with hacksaw.
I also have the new rear bushes into place. I used a large socket to drive them out and the new one in with help from blowtorch, boat club workbench vice and loose oil. Not the "by the book" way to do it but I aint got a press. I usually change cavy wheel bearings with a chisel lol. I can get them out and then use the old bearing collar to knock the new one in! No press needed.
Here's a pic from today of the split bush, will take more tomorrow of the new bushes in place.

It didn't seem that worn really more that it had split. Although I can imagine this causes a lot of deformity once the weight of the car is on it, moving and hard breaking/cornering. I also noticed there seemed to be a split on the front bush when I put a screwdriver in the bolt hole and stretched it I could see the rubber had broken although it really didn't seem that worn or much play in it despite that.
Also got my pop to do a bit of rust descaling on the 2nd arm while I was blow torching the other one. Will update my log for this soon with some other pics as well.
