Undo all the bolts on the top mount (in boot) so you free the top of the shock.
iirc the bolts at the bottom are a 15mm for the nut inside the axle and a 17mm for the bolt head.
Put the spanner on the 15mm nut and brace against the inside of the axle, and then turn the 17mm bolt to undo.
Put a bit of weight on the axle - pushing downwards - and wiggle the bolt out.
Then the shock is free. It may drop downwards through the mounting bracket.
Put your foot on the axle and push down. Bring the shock back through the brackets an lift it over and down. Then you can twist the shock out from the wheel well.
Clamp the springs, remove spring plate.
Fit new springs onto new shocks. Clamp down springs and fit spring plate. Screw on retaing nut, release sring clamps.
Refit new shocks. reversal of removal procedure.
