I think the $45 HEI distributor has a better pickup design. Similar to GM's "small cap" and later Ford distributors, it has multiple pickup fingers all around the reluctor. It seems that would correct for any shaft wobble. Many on here state "Chinese junk", with no basis. As a proud American, I can say that U.S. junk can compete with the best Chinese junk, and much of ours has fancy after-market labels and high prices. Our genius is in marketing junk to the world. If the Chinese were as smart, their stuff would be red (like MSD) or yellow (like Accel).
