Sensa Problems Having A Problem With The Rear Struts On My Car HELP.?

Having a problem with the rear struts on my car HELP.? - sensa problems

I have a 1996 Bonneville and rivets SSEI shot back to back, install brackets Monroe Sensa to complete. I can not have the screws, nuts to bolts, but still. I've tried the outdoor bar and a hammer firearms passport does not matter what I am doing wrong. I have not raised for the rear suspension spring for, but the suspension is essentially the same trip.
