What's the point of the space between the floor and the mount plate- you could tighten the 1/2'" bolt till the space was gone. ????
you know there is a rubber mount in that space right? check the Mid50 catalog for all parts and pieces and how they go together, good pics there.
The pic of the****embly in the Mid50 catalog isn't really correct for a 54- however, they do show the space in the view of the "front cab mount upper cap & plate" (floor line, note space).
Guys, thanks for responding. I called Mid50 with my question, they say Ford built them with that gap, maybe a 50's better idea. If you have not actually replaced these things you probably don't get what the question is.
