Freaked Out By Roof Rust

You could always make a convertible out of it.

What he said

This is pretty much NEVER a good idea. If the OP doesn't have the skills to replace the roof skin, he doesn't have anywhere near the skills needed to turn it into a convertible that will be safe on the road.

Making a unibody a convertible is a heck of a lot more involved that just chopping the roof off. The chassis and body need to be braced, not to mention the finish work to deal with the edge where the roof came off.

Done wrong, you'll have a car that is totally unsafe to drive and that no stock interior parts will fit. Done right and it'll be so much time and money that you could have just bought a 'vert to start with.

As for the OP's car, based on the other pictures its going to be a tough decision. I'd have to see the tops of the quarters stripped down to metal. There might be enough there to salvage the tops of the quarters and just patch the lowers, but that would also depend on the wheelhouses, trunk extensions, etc. And we really need to see the floors. Worst case it needs the roof, both quarters, wheelhouses, trunk, floors, dutchman, etc. The cost of the sheet metal itself would be higher than shipping a decent donor from the west coast, let alone labor. Best case is the roof, dutchman and quarter patches, with the rest being salvageable. But based on how the roof looks, I'd bet closer to the worst case scenario. Definitely not an easy project either way.
