Not sure what your asking, but all the 70 carbs use a manual choke setup (with a cable) so there's no auto choke, or the associated choke hot air tubes. Your carb uses the electric solenoid, so no dashpot either. I'm away from my stuff till the weekend, but if someone doesn't beat me to the punch, I can post some pic's of the right setup. ( I have a 9/30/69 Metuchen 428 AC mach1)
Tons of good info here on the 428CJ site, here's the link, hope Scott doesn't mind...
Your carb should look just tike the one in the first pic....
