what about just chopping the top?I kill Novas for a living and that's just wrong.
You would need an entire hardtop roof, including the A pillars You would also need a pair of hardtop doors, and hardtop quarter pannel window regulators + a complete set of glass.
+ A couple hundred hours of labor. Or you can just sawzall the pillar out and make it look like crap.
You could probably sell your sedan and with the money you'd save just buy a hardtop.
I answered your original question the easiest way I could think to do it.what about just chopping the top?
