Alright, I need some more help with this.
I went to give it a go today without taking the shocks out (limited time frame) but there's no way to compress the spring enough to get the seat at the base of the spring to move. So you're right about that. I'm willing to have a go at getting the shocks out, but I need some more info on the process. I'm told that to get the rear shocks out you need to get the back seat forward and remove the parcel shelf or something? This is info coming from Unique AutoSports in Seven Hills. They offered to do it but said it'd be 3-3.5 hours in labour. Can anyone shed some light?
Even better, if anyone in Sydney has done this and can help me with it tomorrow morning, that'd be fantastic. Please PM me. Otherwise, some info or pics on the process of removing both front and rear shocks would really really help.
