These complete distributors are available from GM: #93440806 and # 88961867 which is the fancy, up-scale, billet, cnc model. 1) Where are these made? Where are each and every component inside made? 2) Do you have any direct (or indirect) experiences and/or comments regarding the above 2 models? Dependability, not performance is my main concern here. 3) P.S. i noticed that gm is also offering a "licenced" model made by proform (i already don't like the sound of this.......) # 141-682. 681 and 683 are just different colored caps. a) Comment on this one as well. b) Pls Don't get it confused with the above 2 models. 4) Can you suggest any other company's models that are as good or better than original gm? 5) And yes, fishing one from a junkyard is another possibility.......... i don't give a damn about performance right now; i'm only concerned about dependability, durability and longevity right now.
