Boba RotJ Right Gauntlet


New Hunter
Hi, I have a question on 2 parts of Boba's right gauntlet. I got a kit years ago and am finally working on assembling them. There are a few details missing from the sculpt.
  1. What can I use for the black rectangular piece (with slightly rounded edges) that is on the top of the gauntlet near the triangular hose input? Is there a part I can use or would this have to be molded?
  2. Same thing for the small tube that extends above the darts? It looks like either a cylindrical metal tube or it may be slightly conical?
