Default Re: No heat from heater 1990 ZR1

So I am back to trying to find the actuator for the blend door. I've removed the dash pad, lower hush panel, console trim panels, etc. Bought a fiber optic scope and still can not find the actuator.

Per the service manual, it looks like I need to remove the distribution duct which involves removing the fuse panel and instrument panel. Before I go forward I have to ask, does anyone have a better way to get to the blend door actuator rather than removing the entire instrument panel?

Below are photos of where I am now. I am really stuck, so please let me know how you have changed out the blend door actuator on a 1990.

Last question is the lower blend door pivot where the read arrow is pointing in the third picture?

Thanks
