?? on Bulgarian Krink Kit on GB

I've been looking for a Bulgarian Krink kit and this one recently popped up on gunbroker.

http://gunbroker.com/Auction/ViewItem.asp?Item=87011251

The owner says it is missing the front trunion and trigger guard. How hard is it to find these parts? Any thoughts or advice on this particular kit? Any input would be appreciated.

for the trigger guard try calling Ohio Rapid Fire and see if they have any more.

The owner just emailed me. It is a virgin kit, missing the listed parts. I really do not want to mess with a virgin kit. I think I'm going to abandon my quest for building a Bulgy Krink 7.62x39 and either buy a Arsenal SLR-107UR or build a 5.45x39.
