Jody at DP Tuners had some black ones, a while back. Not sure if they still do or not. They were the orginal Ford ones. I think they were going for about $75.
Other than that, I am still thinking the old blue one that IH came out with a few years back, did everything the new IH dark gray one does. I just think they changed the plastic, and put a purple o-ring on it. It did retard the timing, with smoothed out the engine lope, made it easier to start, and quieted it down. Sometimes it blew a hole in the fuel milage. It was actually for the IH DT 466, 6 cylinder diesel engine.
Just an observation, I really don't have any idea.
