Bear Kodiak .410 arrow help

[BowHunterGA]

I have a dozen vintage Bear Kodiak .410 arrows. I believe they are basically Bear branded Microflite shafts. Can anyone confirm this is indeed the case and if so can you tell me which Microflite # these would be the equivalent of? I was doing some testing today and they fly great from a Jerry Hill bow that I own and would love to hunt with the setup this fall but I would really like to replace the plastic threaded inserts with aluminum or brass if I can find them.

Thanks in advance!
