94 integra gsr rear trailing arms

I have a 94 integra gsr and my rear trailing arms bushings are broken. I took to a repair shop and they told me i had to buy the entire rear trailing arm and they wanted to charge me 900 dollars for parts and labor. I found the bushing for the trailing arms at JCWHITNEY website. i was wonder how hard would it be to it my self. If you can tell me how it would be great.

well they are gonna be a ***** to change. first the rear trailing arms are bent sheet metal and when you press the bushings out you might colapse the whole arm. i did the front on my accord thou andit took me like 5 days to do it
