So are these Hedman thermal coated 88408? I have a pair too. I have a 73 2 door. I am puttin a 94 5.0 roller motor and thought these are "supposed" to fit. So it looks like you had to cut the flange off....or really "extended" the collector....so to speak. So did this fit well afterwards? Does you car have the power steering box with manual pitman arm? That is what I have. Any help/insight is appreciated. Thanks JerryD
