I have been searching all over and I would like to know if anyone has the measurements of the rear subframe or even better CAD drawings of it on pre-88 Fieros. I have an 84 SE that I am about to start a serious project on and this information would be very helpful. It seems only the 88's get special CAD treatment, and every post I have found asking about anything pre-88 just points to the FSM and the bolt locations which is not helpful. For inquiring minds I will post what I need to replace my iron duke with.
