Hi, are you sure you need new trailing arms? Upon a short google search, I stumbled upon this.
" You do NOT need the entire trailing arm; ALL 88-00 civics and 90-01 Integras take the same shaped trailing arm. You need only the spindle, which is attached by a 24mm nut, and four T50 torx bolts. Please note that most swap the entire trailing arm because those torx bolts are in there VERY firmly. I have banged the hell out of a hammer and impact and still had them stay. I advise air tools, because even with all my weight and brute force, they may not come out. Brake lines may be stubborn if your car is older and rusty. The brake hard lines can strip easily if you do not use the proper wrench. A brake line wrench is what you need, which is a 10mm box end wrench with a slot cut out so that you can slide it over the hardline. You can use this on the bleeder screw too if you put the bleeder hose over the bleeder valve first so that brake fluid doesn't spill. On an EK chassis civic, the bleeding sequence is right rear, then left front, then left rear, then front right. Don't go in a circle, the EK chassis uses a crossed brake system, so go by this sequence to avoid any cross contamination of air into the lines, otherwise you may be bleeding all day. "
