1935 Ford Mounting the Telescoping Part that Opens the Front Window

[Henry Ford IV]

Newest project...mounting the part under the top middle of the dash that extends and opens and closes the front window. The dash is restored and mounted. Please don't tell me I need to remove the dash to put that part in. If so, remove it all the way? Is there a way to partially drop it and fit the part in?

It's called a window regulator.
You can install it without removing the dash but it's a PITA that way. Chance of damaging the dash is real.
