@Deino, 67320 has been identified in 61st Brigade meaning J-10Bs now occupy no. 1-30, and J-10S occupy no. 56-60. This means there's a minimum of 35 aircraft in a brigade, probably 36 if we assume there's a no. 55 J-10S which hasn't been photographed. Huitong has the latest photos available on his blog.
I'm not sure how the 大队/中队 are organised yet.
