New 550B dual caliber setup help please

Sorry for the double-post - I seem to have done something wrong the first time......

Mr. Dillon  (or any other knowledgeable contributor)

I have been reloading .45ACP on a Square Deal B and I am ready to move on to the next level.  I want to buy a new 550B so I can perform .223 and 8x57 (8mm Mauser) reloads.  My goal is for a VERY simple and quick change to change calibers.  I have compiled the list below and want to know if I have all I need to perform an actual quick change between the .223 and 8mm and not require any adjusting or tinkering between caliber changes.  I attempted to follow your automated selection tool, but it left me with several questions on components I may, or may not need.  Your help is greatly appreciated.  Thanks!!
-----------------------------------------------------------------------------------

1) RL 550B   Stock #: 14261 - Caliber Type: .223 Remington $0.00
    Does this mean the 550B will be shipped ready to load .223, or do I need more parts?

2) Dillon Rifle Dies (Three-Die Sets)  Stock #: drd3ds - Die Type: .223 Remington
    If I order #1 in .223, do I need to also purchase this die set, or is it installed already in #1?

3) RL 550B Deluxe Quick Change Assembly  Stock #: 22058
    I assume this includes the powder bar appropriate for 8x57 (8mm), or do I need to change this?

4) RL 550B Caliber Conversion Kit  Stock #: RL 550B Caliber - Caliber Type: 8 X 57 Mauser
    Will these dies be installed and set in the tool-head by you before shipping?

5) Powder Funnels Stock #: Powderfunnels - Type: "M"8mm rifle - $0.00
    Does this need to be ordered in conjunction with #3, or is it included for 8x57 (8mm)

6) Powder Funnels Stock #: Powderfunnels - Type: "A"- .22 caliber - $0.00
    Does this need to be ordered in conjunction with #1, or is it included for .223

7) Dillon Rifle Case Gages  Stock #: drcg - Dillon Rifle Case Gages: 223 Case Gage
    Is there such a tool for the 8x57 (8mm)?

Additional questions:
    Do I need to also purchase any new shellplates or buttons?  Or are they in the kit?

    Am I missing anything else to perform the quick change between these two?

Again, thank you for your assistance!

When you order the 550 B it will come with the quick change die plate but the dies will not be mounted on it. You will need to mount the dies and adjust them for the caliber you are loading.

The quick change assembly (with the powder measure will come with both the small and large powder bars. Depending on powder and load will determine which is correct for the caliber you are loading.

Generally the powder funnels come with the caliber conversion that you are ordering. Any questions give Dillon a call direct on the 800# their guys are excellent on the phone with these types of questions.
