Where the %$$#&^ are my polycaps!?

Just got some kits in last night.  One was a Wave VF-0S and I decided to dig in and work on it at the same time as the matching VF-0A that I started a few months ago.  Only after opening the bags did I realize that something was missing.

I figure ordering replacements from the factory isn't an option and most of the parts aren't standard shapes I can order form HLJ.  Since I opened the bags the trees were in I obviously can't return the kit ( and shipping back to Korea for an exchange would be a bear even if the seller was OK with it ).  At this point I'm looking at either ordering standard poly parts and modifying the kit to accommodate them, or making it a still figure using Milliput or some such for the joints.  Any suggestions on these approaches, or alternatives I may be overlooking?
