I'm not a tech guy either, but. At WoS I was gigged for not having my net inside the cage on my steel body Vega. Later Gary Cope, the inspector in question, called to say he had reconsidered and that in the case of a Uinabody car such as my Vega, the net being attached to the inside of the door frame was good enough. This was confirmed by another well known SCTA person. That said his write up made me look at the car more closely and right now I'm taking a lunch break from moving my clutch pedal to a better protected place and I will be looking at moving at least some of my net mounts inside the cage.
