i put a little slippery stuff on the the metal to metal parts. inspect and test fit everything first, it would suck to get a bushing in and then learn that the pin hole is all sloppy AF. go slow and steady and try to avoid using the threaded end of the pin as a press point, it'll F out the threads and likely the pin will go in cocked and you'll get to buy a new bushing and do it all again.
