Im getting a replacement stock for my Series 6 Arisaka and i'm curious if stocks of different series were ever miss matched with receivers during the war?

Type 99 stocks were not numbered, so there's no worry of a mismatch there. Stocks did vary according to which arsenal / subcontractor they came from and which series from that source they were. Stock final inspection marks varied also. No, they were not mis-matched.
