I have both sets. I probably don't know what I'm talking about, but I was told that the two different lengths was that the one that is deeper was made to accomodate the trim on Senior '52 &'53's.

I have the smaller brackets on my sedan and they seemto work fine. I even have the necessary gap between visor and roof to allow air to escape. This car has been run at 126mph with nary more than a flutter of the visor. They work.

I bought the longer set (or deeper I should say) brackets from Guy Spring for the convertible, because the short brackets made the top edge of the visor slam hard against the trim around the windshield. Now, I have the necessary gap between top of visor and windshield. The other difference I noticed is that the visor on the convertible has a much more sinister rake to it (which I quite like), but makes the viewing area even smaller and more tunnel-like, which a lot of folks don't care for. So far, this car has been tested at 5mph in the driveway, but seems to work well, regardless.

I just got a new camera for the Nationals, so let me go snap a few pics and I'll post some images to go with my ramblings.

Here's a few pics:

Russell,

Fantastic pictures! [img] [/img]

The difference now is easy to understand. The stainless bracket is simply longer.
My car has the stainless gutter which needs the longer bracket.

Off to look up Guy Spring.

Thank you for the help, I appreciate your time!

I bought a set from Bent Metal (Mr. Spring) and they were works of art! Highly recommended.

David,

Thank you for the recommendation. 🙂

I spoke to his wife last night and ordered a set of the brackets.
