Polyurethane Sway Bar Bushings Any Body Installed Em??

So I bought one of those polyurethane suspension kits from Energy Suspension, but they didn't offer sway bar bushings, so I got a set from PST. My question is, has any body installed a set of these? There are no instructions and they look like they will be a fight however I go about it. Also anybody know where I can get the round rubber bumpers that the upper control arms come down on, not the ones on the lower control arms. Thanks.
