I searched and searched but i couldnt find anything on this thread.I was told in order to install the eye bolts for the 4.0 harness, you would have to drill a 7/16 or 1/2. But my question is would i drill on the backside bolts of the seat or the frontside? Because when i purchased the takatas from lancershop, the order included a set of eyebolts that the thread wasn't even close. Plz help thanks
