Hi, I got the gas rams today, and armed with a 12mm spanner and a small flat screw driver I set to work... now the rams are held on by an E-clip at the boot end, and the ball joint at the car end. after removing the e-clip with the screwdriver, and being careful not to launch it down the drive when it twanged off, I then undid the ball from the car with the spanner, and about 3 minutes later one ram was off..

Retreating to the garage, as it was warmer, I then proceded to remove the ball.. well, I would have done had it not been for a design feature by honda... inside the gas-ram 'cup' there's a small snap ring ( and NSX's are famous for them!) when assembling the joint, this snap-ring butts up to a square edge, the circular ball eases it open, and it 'snaps' together.. all fine and dandy.. however, if the ball is pulled out, the snapring is pulled up a taper, locking it solid, effectively a one way joint the ball can push in, but not pull out (unlike every other ball/socket joint in the history of engineering!). Not a problem, my struts are useless, so no qualms about a quick saw cut and the ball is free! the re-assembly is simple, screw the ball back into the car, slide on the top joint and refit the e-clip, minding your fingers, and just snap the ball joint together, easy!

Repeat for the other side, with the extra bit of removing the wire clip for the brake light! I done this all holding the boot up with my head, though you could use a broom handle or willing volunteer.

All in all, with the added time of cutting the balls out... about 25 minutes total, if you buy them with the balls aswell, you are probably looking at 10. Not complicated in any way. Obviously it will take longer if you have to look for a launched e-clip!

So, I hope that helps, and recommend buying the balls as well, it'll make life so much easier!
