Need to replace bushings on a rack and pinion

GA16DE GXE. While replacing hoses and rear motor mount. I found what was left of the bushing for the Rack and Pinion. I purchased replacement bushings came with two one circular and the other non circular with a triangular point. Need to know how to replace them. Just before doing so on my own since the passenger side of the Rack and Pinion, I can see that there are total of three bolts lined vertically holding up a metal band looped holding the Rack and Pinion. If that's what I need to do in order to grease the bushing with suspension grease and loosen bolts to get the bushing around and through the metal loop/strap then tighten up? Wanted to know if I'm on the right track.
