chevy52,
I am interested in visors also. I have a AD truck and have watched E-bay for these items on and off. The '52 has the two piece windshield, visors AND parts are quite abundant for this style truck. There are also aftermarket NEW ones available.
I think the roof line of the car was much less steep in the attachment area than the pickup. I am not sure, but I don't think they will interchange.
There is a member of this forum that is visor-wise...he will probably be along shortly to answer your questions with authority.
I think if you look in the tech tips, you might find installation instruction. I know I have seen them for the Fulton brand on several sites on the web.
