Yes, but it is not without some work. The two arms of the '40-'41 swaybar must be bent inward to match the axle pin location of your '36. The '40-'41 axle pin is longer than the '36 so it must be re-drilled for a cotter pin and some extra threads need to be added.
The best way to add a '40 sway bar to your '36 and keep a factory-like appearance is to swap an entire '37-'40 front axle assembly for your '36. This will allow for a bolt-in of the '40 swaybar. As an added bonus it spreads the wishbones out making it "somewhat" easier (still a nasty job), to remove the oil pan. This is what I have on my '35.
