Primer size swap

I got a 550B from a friend and he didn't give me all the stuff like small powder bar, small primer system parts and stuff and I am wondering what parts I actually need to swap out to switch to small primers from large, I know the magazine is different size and I know I need primer pick up tubes, what else needs to be switched? He was loading .45ACP and I am switching to 9mm and .223

The primer slide or bar with the primer cup. This part picks up the primer from the primer tube.

I ended up just getting a spare parts kit and it had the replacement parts for it, I was going to order an entire primer assembly or whatever for like 25$ I ended up getting even more useful stuff for a couple bucks more. Thanks for the reply

Or you can do like me, get a second 550. One for small primer and the other for large primer.
