Thread: What are these for?

Tweet

I recently bought a completed 1930 Brookville Roadster and just noticed 2 snap fasteners on the inside of my convertible top (see attached photo) What are these used for?

There should be three snaps total.

They're used to retain the rear window in the up position during hot weather.
With the rear window open it makes for excellent air flow inside the car.

Be advised, that running a top will create a low pressure area within the cockpit and you'll suck hot air from the louvers into the car through the door gaps.
You need to weatherstrip the doors

Note top in photo has the rear window open.

Those are you basic 12-2 Alpha-Delta-Charlie.
Basically.

C9X...THANK YOU SO MUCH!! (That's right, I'm shouting! (LOL) I had no idea the back of the top was able to open. Cool!

Like I said, I'm new to street rodding. I purchased the car in December and had no idea what they were for. Thanks again for clarifying.

You're welcome.

Don't forget to weatherstrip.

I know, it sounds weird to have weatherstrip in a roadster.

When you're driving 25-30 mph or so, stick your hand out the window and get a feel for the ambient air temperature.
Then lower your hand so it's down far enough to catch the airstream emanating from the hood side louvers.
You'll note a 20-30 degree (F.) temp differential in summer weather.

You can also drive the car in shorts and you'll feel the hot air coming in the front gap hitting your leg.
And feel hot air coming in the rear gap and going straight up your side.

Not so noticable if you always wear Levi's or long pants, but your shorts wearing sweetie will notice....
