don't go cutting access holesin your floor, it is unnecessary. when the bolts for the rear shocks snap just grab the puch and hammer out of your toolbox and go at them from the bottom side. they will eventually "pop" off leaving you nice holes to drop some new bolts through. before you go mounting up those shocks try this... if you have a rear sway bar, which more than likely you will not reuse, take the sway bar brackets off the top of the spring packs, flip them over and mount them up in place where the shock would mount. now you can eliminate that ridiculous "bayonnet" style mounting pin and just run a bolt through the old swaybar mount/ new shock mount. this way when you go to change out the shocks for bigger ones when you decise to install a bigger lift in like 3 months you will only have to undo the one upper bolt on each shock. there is no need to go butting the floor. this is a frustrating job but you can get r done with a little patience. plus if one of your helpers has small hand, this is the job for him/her. the acces areas to get to the back side of the bolts is quite small up in the uniframe but accessable. one more thought, when replacing the 4 bolts, 2 per upper shock mount, drop the bolts down from the unibody, they are easier to hold onto with a wrench than positioning a nut up there where you cannot see. good luck!
