How do you replace shock absorbers on a 2006 SC430?

I've searched and searched and have not found any information on how to replace the rear shock absorbers.

Has anybody done it before or can point me in the right place?

A step by step list would be great, or with pictures would be even more useful.

I'm confused as to how to get to the top bolts? On other cars you would remove the rear seats and there's the bolts. On this car, it seams hidden pretty good underneath the trunk.

Also, what's a good website where I can get a good price on OEM struts?

Thanks in advance and sorry if I asked something that's already been discussed.

 

The location for those top bolts are under the carpet liner of the trunk. I don't have a picture of my trunk taken apart or with the liner removed (surprisingly), so can't show them to you specifically on my vehicle. After you remove the trunk liner, those bolts can be easily accessed. There should be an older thread about doing coilovers, that might show the location of those bolts. Hopefully, one of the members may have a pic with theirs removed & chime in
