Trying to find a Vietnam War usmc flak jacket

[HOOKED ON HISTORY]

Trolling ebay ,shows and surplus stores building a m56 web set. I found a great set of suspenders excellent shape and cheap (for someone 5' tall) but did score an early mag pouch with two 20 rounders. The butt packs are selling cheap enough on ebay when I am not watching but high when I am. I think the airsoft folks is who I am competeing with.
Update I think the suspenders will work. They are supposed to attach to the butt pack which will make them long enough ( I hope).
