I made a small tool out of few washers, nut & bolt, and a home water pipe nut to press in the bushings. Took me about 5 minutes to install the second one that's tucked above the exhaust line include the time to crawl in & out - no cuts/slits ( but that's after a few hours trying to use a vise grips, pliers... *doh*)
