ok that's good to know. But the 1" shorter length is going to reduce steering quickness if I compare the same steering gear with the 6" long pontiac pitman arm vs the 7" chevy camaro pitman arm. I don't want to loose steering quickness else I would swap the entire firebird steering setup with the new tie rod ends onto the 79 Z28 I have. I am also building an 80 Firebird so the new tie rod ends won't go to waste either way, but the Z28 is what I am putting on the road first.
