Bought a rolled 09 Honda Civic. The roof is partially collapsed. I want to turn it into a convertible. What ragtop and frame will fit?

Whoa.

I'm no expert in the matter, but even factory convertibles are notoriously leaky, noisy, and unreliable. I can't imagine you're going to pull this off any better than the manufacturers. I think you may have wasted some money (not much, hopefully) and gained a liability.

If only it was that easy. You have no idea of the time and labour involved. You may as well say you want to turn it into a helicopter.

It's not just a top. There are rocker boxes and frame stiffeners that convertibles have to take care of the structural integrity the roof provided.
You are in for a job.
It will all probably have to be custom built for the car.
You can use a tannoue cover like on the bed of a truck or old Brit sports cars to drive it around.

None. A convertible's construction is much more than a chopped roof and ragtop. A convertible has body differences to add support and strength that a roof normally provides. You can't easily duplicate that, if it's even possible at all. You might be able to do a hack job but I doubt the car would ever be street-legal.

Do you know what a unibody car is?

Your car will buckle when you hit a pothole as the roof is part of the car's "frame".

I was going to answer but I can't stop laughing long enough…
A hacksaw convertible, woopee.

Use a measuring tape and measure your car width and length. Write down the measurement on a piece of paper and visit a junk yard and check out what is in there. You probably want to go where the foreign cars are kept. Seek and measure it out. Maybe you can find something or maybe you got to make it yourself by bending tubing and having a cover made for it. I have seen cars cut up that way to be a convertible.
My factory MGB was tight, not leaky and noisy because of the "Blue bottle" muffler under it, it was meant to sound like a sports car. Screw hearing the radio. It was rappy sounding. The sports car sound.

Study or take pictures of various ragtops you find in the junk yard to see how the convertible framework was assembled because you may have to build one from scratch.

That needs a custom built
