CPP sells a modular spindle that works with factory size disc brakes with a bolt on caliper bracket.
But why do it twice?
Does it need brakes to be in the body shop?
Install the wilwood stuff without the front rotor or caliper.
Bolt the wheel to the hub or just leave the caliper off.

Is the qa1 stuff going on before bodywork? What’s the big picture plan?
Multiple rounds of primer will kill a detailed frame unless your body guy wants to tape everything off every time. Not many are that energetic.
Plus you will pay labor for that.
