building new pulling truck

[mcmullentrucks]

I am building a new pulling truck, it is a 99 F-350 with a 7.3 diesel. The one place i want to run requires a crankshaft damper shield. Any ideas on what i need for this. Also they want a kill switch, what is the easiest way to do this.

Kill switch would probably have to be air shut off. You can find kits online or make one
