The pylon for the YJ-91 on the j10c seems very weird in my opinion, as i have never seen it before. However it could be that i am simply unaware of this type of pylon. If anyone has pictures that show this specific pylon please show them.
The Kd 88 in game is mounted the same way, but i can not find a real picture of it to compare with.
I did find this picture from model instructions about the DF-4 and DF-4/3 pylon that claims that the DF-4/3 pylon is specifically the version adapted for the J-10.
