Zac, That Bell Jet Ranger kit is pretty old. You may want to start your own thread over on Aircraft for your request. Since you posted here, and as I have no update for the OPs Victory, here's my thoughts on Heller...
I usually look around once a week or so for Heller ship kits on eBay, Goodwill, Lots-of-models and Charlies plastic models, and with Google searchs. One of my efforts turned up the kit you need parts for.

Buying another kit may be the only option if you can't scratch-build or find these individul parts. This vintage kit is listed as 19usd but shipping to NZ may make the cost prohibited, as you mentioned a lack of funds. During my time here at FSM, ALL the members have helped out with info, photos, missing parts, and instructions to assist other members accomplish that Impossible Dream. Hope that happens here for you.
