Missing piece on vacuum modulator?
Why is this vacuum modulator missing a piece? Is the new one the wrong one?

😆 figured it out. It's for a turbo 400. The extra piece gets removed for the transmission. I found the manual on my workbench. Must of fell out the box when I removed the part.

Looks like your old one is an adjustable unit . I just bought a red strip for my TH400.
