RL 550b caliber conversion question

I have a Dillon RL 550b reloader and I would like to change over to reloading .223 for my AR 15.  I need to know if I have all of the right parts be for I place the order.  Here is what I think I needed:

RL 550B Deluxe quick change assembly 22058
RL 550B caliber conversion kit 20128
Dillon carbide rifle dies .223 remington 3 die set 10096

Am I missing anything?

Thanks

I suggest a headspace case gage #13254, and if you don't already have it, Dillon Case Lube #13733. Otherwise, your list if ideal!

Will I need a case trimmer?  its mentioned in the gauge specs

Cases require trimming typically after two or three firings. A trimmer will be needed eventually, but not right away.

Thanks for the information, any tips for the case lube, I have never used it as I currently only reload 9mm and 45acp.  This is new stuff for me.

With a straightwall case, you can use a small ring of a low-friction material such as carbide to size the case; the ring is only a small segment of the length of the case, so sizing doesn't develop enough friction to cause a case to stick in the die. A bottleneck case, must have the die contact the entire length of the case in order to resize all of it. Because of this, the material the die is made of does not reduce the friction sufficiently to allow sizing without lube. So a light coating of lubricant, in our case lanolin, prevents the case from sticking in the die. Insufficient or no lube results in the the rim of the case pulling off before the case can be extracted from the die.
