With any luck I should be on tonight (10pm EST). If you still haven't got those heads by then, send me a message and I'll help you out.
Ouch, That really sucks. I killed bunker 4 times in tvhm and got the Space Knight head.In hindsight I probably should have made a copy, but meh. Good luck.
A space knight head but if you ever get the other one make a copy and send it this way please.
