9” drum brake retainer clips on assembly line, OEM?

The drums on the front are swedged from the factory they were only sold as a service part by Chrysler that way. If you need to separate the drum from the hub the swedge must be cut off first if you try to press out the studs without cutting off the swedge you will F up your hubs. The correct tool to cut them off is no longer available, most people use a 5/8 metal cutting hole saw minus the pilot drill to do the job today. I believe the drums themselves are still available. I thought someone did a how to article on this. Proceed carefully you have been warned.
