energy suspension

I attempted to install the energy suspension bushing motor mount insert kit in my car today, but the passenger-side inserts did not fit inside my stock motor mounts. Has anyone else had this experience? I have a 1997 Civic EX (d16y8) and the kit was part # 16-1105. According to Energy Suspension's website, that is the correct kit for my car. Are you supposed to modify anything before installation?

I installed a short throw shifter and ever since my shifts have not been great. Sometimes at lights, I can't get the car into gear, so it was recommended that I install the energy suspension kit and the neuspeed shifter bushing kit too. The neuspeed kit was great, but the energy suspension kit won't fit.

Any suggestions?
