I got a Box of old style Space marine terminators, 5, and 2 of them got Heavy flamers, atm unassembled. Since I started painting up some Space Wolves, I thought to use these as wolf guard, but since the new rules don't allow a pack of 5 terminators with 2 flamers, I thought to convert them. Would some weapons from forgeworld work, or some spare weapons from a pack of new style wolfguard? What would work best to convert them to playable wolf guard?
