Correct, no other way unless you weld in one of their housings somehow.
OK. The way you worded it, I thought other companies did something different. I thought the DDB was supposed to be a direct replacement for all factory Clevite on the TJ. So I assumed they would just press in the same as the Clevite. I think they even have an option for factory TJ control arms. But that was some time ago I heard that and I never looked into it.
