I didn't have to much trouble getting mine on.
DONT CUT IT!
Take a screwdriver and stick it through the EYE. making sure the boot is stretched under the screwdriver. now take a flat tip, stick it under the boot perpendicular to the other screwdriver and use the metal part of the eye as leverage, push away from the shocks (to stretch the boot) and it should just slip right into place.
[edit] I did have to use some force to get it under the eye, the boot seems to be strong enough to handle it to not tear.
