I'm almost sure that with 96-00 Civics you can use your stock mounts for B series swaps. But I would highly recommend upgrading your driver side motor mount. The stock mounts on that side are super weak, hense why I have a massive dent in my hood. Others will probably chime in about the lameness of that mount. If you are on a little bit of a budget, I would recommend the passwordjdm driver side motor mount. I'm pretty sure it was like 149.00 or something like that. I have it for my car and the motor doesn't move at all. Hope this helps you out, if you need anymore help just PM me.
