What is this type of car called?

Hey guys.
I'm debating on something my dad keeps suggesting I do with the dart.
He thinks I should cut the roof entirely off, leaving only the windshield.
No other roof, pillars in back, nothing.
No convertible or top of any kind.
He keeps calling it a "California cruiser "
But I can't seem to find anything on that name.

I'm playing with the idea. Might not be to bad.
With no roof I suppose you don't need side glass.
Electronics may get sketchy(cant really have thousands of
Dollars in electrons with no protection)

Cutting roof away, you would definitely need a good subframe.


Anyway, if someone can explain this or point me in good direction.

Thanks.
