How to do, first take the rear seats out, then take the side trunk plastic panels and rear side speaker panels out, then the rear side window panels out, that should give you access to that mounting area. make sure you dont pull too hard on the panels which means, there a bolt there somewhere. this job should take 2~3 hrs if you know your way around the car or 3~5 hrs if your new at it.... it a bitch, I know...
that was a video I made for their developer, AVM industries. I've had those prototypes on the car for a month now and have had no problems with them at all after sorting out the initial issues with them regarding their fitment. I don't know when they'll be out on the market, but I'll let you all know. their hatch shocks for other models typically go for about $110-120 a set from my observation, so hopefully the ones for our cars will go for about the same price range.
This thread is old but I just thought I'd add my MacGyver method for anyone interested... I replaced mine yesterday. I bought struts for a MKIII and reused both the top and bottom mounting brackets from the OEM struts. Total cost was under $50.
You probably wouldn't be able to do it without the right tools and equipment... but I cut off the brackets and ground them down to be flat, drilled out a hole for the new strut, and used a nut with locktite to secure the new strut. On the other end I used a dremel to release the ball from the OEM socket, then pressed it into the end of the new strut.
Buying new ones from Toyota would be the easiest route but this method wasn't very difficult either. I just wanted to make something that would work so I could knock it out and move on.
