Hey guys while you are checking numbers do me a favor if you can. On the 86 cars there was also a build date etched onto the intercooler up on top with the decal. Could you early 87 guys check to see if they were still doing this on your cars. I already know most of the 87 build year cars dont. Also if you are missing or cant read your door tags you can also find a build date on the frame. Look on the rear crossmember in front of the rear axle. It is stamped in the area where the right up control arm mounting point is. I've included a picture on what my 86 GN looks like. Thanks,
Edit,sorry guys I'll have to post a picture that you can enlarge later. And this is from an 83 T-Type and not my GN. But the number is still there
