Here's one for ya. My '58 Packard has this little pedal on the drivers side. It's not an emergency brake. My best guess is that it was for the washer fluid(?)
My '56 Packard 400. Rebuilt #matching 374 (warmed up a little) adapted a TH400 to it. Still working on it.
Did they come with the supercharged Studebaker engine?[/QUOTE] Yes, I believe they did. Mine was switched over to a 4 bbl. Carter carburetor by the previous owner (I'm the 3rd owner).
