In regards to the A/C system: D.3.e "Air conditioning systems may be removed in whole or in part" Are you not covered there?
What are the odds of getting a change to address this? Does changing accessory brackets, moving an engine mounted accessory and/or changing belt routing open any pandora's boxes?
You know me - don't race under weight, have an IT legal motor, drivetrain, chassis, suspension, and I think you're good. I could care less what you do with wiring, pulleys, washer bottles, AC, motor mounts, bushings, tranny mounts, etc., but I don't make IT rules.
Question - what are you trying to solve?
