Few KI-84 parts that were on EBAY.
Typical bloody eBay. Those parts were advertised as NiB

Although it pains me to disappoint a fellow Ki-84 fanatic, I'm sorry to inform you there was no version of the Hayate fielded with two 30-mm cannons. The model which you describe as the -Ic carried, in practice, a single Ho-155 30-mm cannon in the starboard wing, nothing in the port wing and two Ho-5 20-mm cannon in the cowling. The single installation reflecting the availability of this weapon which was only entering mass production at the war's end.
Have to correct myself. The 30-mm was in the port wing. A typo in the original text is to blame which is often incorrectly quoted. Apparently also by me five years ago.
This would of course make a profound difference in the flight modelling
