My 66 Bronco has an NP435 with the Dana 20. Which shifter do I need? I don't see where any of your shifters work with the NP435. Thank you.

The NP435 uses the same twin stick kit as the 3 speed and C4. See part # 8573 or 8557. Add kit behind the respective # 8573kit and we have a kit that includes the shifter, tunnel cover and boot.
