Welcome Camden!
try to look in the For Sale or Trade thread periodically. Forum members sometimes need to dump their untrimmed armor in a hurry. You might get lucky!

in the meantime look for and gather stuff that’s within your means, e.g. tools, soft parts like the undersuit, elastics and snaps, adhesives or glues, etc.

and have fun in your research!
