I happen to own one of the "fury" nosed B bodys, so i came across this also. A "Sport charger" had the fury nose, the other "Chargers" got the cordoba nose. Mine is technically a 77 monaco 2 door, but has a 75 RR nose. bolted right on.
is it like the ones that were in some of the "Hunter" TV episodes? I liked those. Sometimes, you could hear the Thermo's opening the secondaries on the TV chase scenes. Awesome sound effects, hahaha.
