Hello to all! Well, I ordered two parking light lenses and gaskets...problem is they are way too small and do not come close to fitting. What year parking light housings are these? The truck is a '53 but I'm not thinking it's parking lights are correct.

 

That is a 55 or 56 parking light.

 

That sure looks like a 51 - 52 lens.

 

Here's a different view.

 

You have a '55 or '56 housing and bezel.
