Review on Hedman 88350 Standard Duty Uncoated Hedders by James Jenkins

Difficult to install but they will fit. (Mustang II 1978) They come with 2 "cut tabs" to allow you to detach one of the tubes (they have slide bushings for this purpose). For assembly I had to cut off both tabs (left and right) and unscrew one of the motor mounts. Remember you need to find a double hump or awesome powertrain mount. I found one on ebay.
