the bolts in the rear were pretty hard to cut off. my friend only had a saw zaw so it took a good 20 mins to cut each bolt. he went through at least 5 blades try n to cut the bolt off. after he got the bolt cut off he took the whole lower control arm off from the car and then used a butane torch to melt the bushings then he hamered/chiseled them out. Installing the new bushings is a piece a cake. just spray some WD-40 on the edge of the bushing and used a regular vice grip to push the bushing back into the lower control arm.
you can probably get this bushing at your local honda/acura dealer
