I pulled a pair of GT40P's for my '85 Mustang a few months back and ported them per the info below. Evidently it's easy to screw them up by cutting too much and in the wrong places. I did exactly what was descibed in the article and no more.Well this weekend was 1/2 price weekend at the Chesapeake Pick-n-pull. I was able to retrieve a set of GT40P's from a 2000 Explorer. Only cost me $52.00 (and some change). They are in great shape!!
