Only thing that comes to mind is perhaps contacting some of the AK 'smiths and seeing if they're doing any 84s/Krink conversions. Every now and again, folks will sell of the 84s parts to cover some of the cost of the build. (Look at it this way, the only reason they bought the 84s was so their Krink could have pre-ban features, good chance they don't want to invest in a post-ban .223 build)
I've got an 84s set I've been meaning to get to the guys at ORF, it's just been a tough season for me between the rain, the rain and the rain... Well, that and the thieves that got into my truck and stole my tools. [rant mode from hell] Damn crackhead/tweeker types, wouldn't steal a tool to work with, just damn dope money at the pawn shop![/rant mode from hell off]. Yes Campy, the bastages got my beloved new Stihl as well and I ended up about $50 from an insurance claim! It was almost enough to make a person 'fudge' the paperwork, I just couldn't do it....
Anyway, back to the point, the 84s is a dandy 5.56 AK and unlike the standard post-ban Norinco, you would have the cleaning rod retainers still attached under the gas block and fsb. If you find parts the price should be reasonable, I've seen 3 sets sell for less than $150.
K-var still has Bulgarian stamped 5.56 kits complete minus receiver for $430, something else to consider.
