68 Dart GTS Bigblock Prop Valve Heat Shield

Thanks, appreciate the help. This solves the mystery. I have a 68 dart GTS. The valve is original to the car so everything should fit.

Is that wiring clip the same that mounts to the alternator?

Pretty much. They are listed as different but physically look the very similar. One has a longer middle prong..

First is the alternator second is the brake warning wire.
