anyone replaced liftgate cylinders

[duboy]

I tried searching to see how this is to be done, but couldn't find much if any info. My liftgate no longer stays up and i suspect the 8yr old shocks/cylinders/gas struts whatever you call them are to blame. I looked just now in the dim light left in the day, it's not obvious how they come off. it looks like there's a metal band that perhaps needs to get popped up which will then release the shock/cylinder/gas strut thing from the mount points. Can anyone point me in the right direction?

i see it as part 6 on this diagram
