Does this mean the the chrome housing I found on the internet is from a '51-'52 Chevy car? and will not fit the '54 chevy truck?

I was a little unclear on the answer. I guess I'm an old slow learner and fairly new to the discussion of optional parts available on my '54 PU. I purchased a refurbished original clock but can't find a housing to mount it into.

I don't want to buy something that won't work.
