I'd start at
Post 137 for the jacket embossing. Also, look for a video near the end of the thread. I started doing them because it was easier to post.
Actually, turn the sleeve inside out and find the seam. Get a seam ripper and carefully insert the point between two of the stitches and put tension on the fabric by pinching and pulling it against the blade of the seam ripper. Once that first stitch gives, pull the fabric away from the stitch. The rest of the process is tedious, but easy. Make a gap big enough to turn the sleeve inside out through the hole you have made.
To sew shut, look up 'locking stitch' on YouTube, (hey, you gotta' do some of this on your own, Amirite?).
About the element guns, well, I used what I had, (Nerd quad-blasters). I'm fairly certain that there are 3D print kits that are narrower, which may work better for your size. Anyone following this build who knows an RPF member who can get a link put up, here, I'm sure
MrSouthpaw would appreciate it. (I'd do it, but I'm posting from my phone and the entry field is freekin' narrow) #lazy

Did your Element Gun mods end up making them significantly shorter? I may do something similar since I am almost a foot shorter than Pratt (5' 4"), and shorter guns would probably look better proportioned.
How/where did you cut into the jacket liner and how did you sew it back up? If it's in this topic I missed it.
