Without knowing your ability or budget, but, speaking from experience... I tried tackling this job years ago with friends who had done this work before and we stopped before we made a mess of my car. We broke two bolts trying to spin them out in order to upgrade the mounts to poly. I ended up finding a metal/body repair guy to do the work and he replaced all the body mounts with the energy suspension poly kit. I'm not saying its impossible to do yourself and also not doubting your ability, but, this is one of those projects that can turn into a pandoras box of problems real quick.
