Hi Eric.
As was stated above, the version of Boba Fett that it looks like you are leaning towards is from the Book Of Boba Fett. Which (I don’t believe) has an approved CRL yet. When you contacted me on Messenger, I didn’t realize that you were looking to get approved. I thought you were just making that version just for yourself.
The most recent version that does currently have a CRL is the Mandalorian - Season 2 - Repainted (aka Boba Fresh or MS2).
This costume is almost entirely different from the Book Of Boba Fett costume.
Boba Fresh/MS2 is the version that I was approved as. If MS2 is the version you are meaning to create, then please reach out to me and I can help guide you to the correct articles of armor and accessories that you will need. Unfortunately, the current armor and accessories that you have acquired are based on the B.O.B.F. version wishing is currently not an approved 501st costume. - You can continue your build in this version, but you will not be able to apply for approval until (or if) a CRL is released.
But again, if you meant to be perusing the build for the MS2 version (the same one that I wear), let me know. I can definitely help you get what you need to get this version approved. Just let me know. I’m glad to help and share my knowledge and experience.
here is the link to the MS2 Fett CRL:

Let us know if this is the version you meant to start on and we can help you get in the correct path.
