9 inch hubs?

I had to learn this lesson the hard way. I wanted to convert my LH threads to all RH threads and took the new studs to an experienced brake man. He pounded out the stud and ruined (enlarged) the hole in the hub. Then I ask questions and did my research on this forum.

I found out about the "swedging" installation. It is really quite interesting how Chrysler and some Fords were done this way. Chrysler felt that it would make for a better assembly if the drum and hub were pressed together. There are different methods to remove the studs, but pounding them out is not one of them. I hope you haven't ruined the holes yet. Good luck.
