Ok, I know it's 9 years past the original date... but I just swapped mine out and I'd like to offer the pearls of wisdom I learned today. First off, I ordered StrongArm 6191R Toyota Celica, Hatch (R) Large Spoiler Lift Support and then 6191L for the other side. Now, the fun part... was using a 10mm socket to get the nuts off on the car. Then I used a 12mm wrench to try and get the ball off on the hatch. Now, make sure you've got the hatch propped or a buddy holding it. But, do NOT leave it on the little tab that holds the string for the ledge. I had a 2x4 at an angle and it broke off... so now I have another thing to fix. But, after I've managed to get these on I'm soooo happy with them, makes me wish I did it sooner. They now just automatically lift up after 6 inches, it's great and only $60 for the pair. I highly recommend them.
