Nice man. Do you have the newer revamped C5's that replaced the XR's?
I personally didn't remove the door hinge limit for my build. I just pulled out both sides of the Boot. The side that connects to the cab is kinda 2 part. It has an inner plastic ring that pops off. This Makes putting the boot back onto it a breeze. When your'e done it will snap right back into place no problem. Unfortunately I'm kinda lazy and didn't take as in depth pics like you have lol.
