How to make a coax or a weapon station mounted on a turret that can be managed by BDA and rotated with the turret?

[BlindSniper0393]

I'm always trying to create armored vehicles or tanks that exist in the real world in the game,like M1A2, T90, ZTZ99A, LAV-AD and so on. In order to achieve functions such as optical lock and mouse pointing shooting, I added BDA mod and some BDA expansion packs such as FoxDefense and KBF to the game.Then I got a question: Despite the primary weapons like tank gun, many armored vehicles also have secondary weapons like the coax and the weapon station on its turrent. Unlike reality, in the game I always can't attach the parts I need to the turrent parts. Even though some mods allow me to attach parts on turret parts, it won't rotate with the turret. So I want to ask if there is a solution or is there any weapon mods of KSP1 that allow you to attach parts directly to the turret and make them rotate with the turret?

 

Damn it. Looks like I have quite a lot grammatical errors
