As already stated, Corvette's have always been produced on a frame. A unibody is basically a car constructed without a frame as you would think of a frame. It uses the body and panels as the frame of old.
As far as repairing a Corvette that has been in a wreck, that is a hard question to answer. If the frame has not been bent then it can be as simply removing the damaged parts and replacing them or repairing the existing part with fiberglass matt and resin. I repaired the rear quarter panel on my '66 many years ago.
How ever if you are not well schooled in body repait, I would suggest leaving it to a professional.

A unibody really means the body and it's underpinnings act as the frame and hold the car together and provide its strength and rigidity. This saves weight since the frame normally weighs so much. But with a fiberglass or plastic body, it would be very hard to do and have enought strength.
It's mostly trucks that have frames now days.

a great explanation of the process (and the innovation at the time) can be found in the book "all corvettes are red". it should be required corvette reading, particularly if you have or are considering a C5, or just a corvette "history" buff. great insight into GM and the development (or lack thereof at times) of the C5 into a production vehicle.

Frames ?
Starting with the C5 the metal frame is 'Hydro-formed' or in plain words, it goes into a tube and pressurized at 10.000 psi. The method of forming the frame is such that it doesn't deform or destruct the metal molecules and gives you a better frame in rigidity and consistent shape & then galvanized. But the book goes into much better an description.

And with less welding involved, there's probably a significant savings in weight in addition to structural rigidity. To bad the C5/Z06 frame wasn't aluminum like the C6/Z06.

You can frequently find "All Corvettes are Red" and "Corvette from the Inside" as a set for a good price on e-Bay.
Gives you great insight into both the C4 ("Corvette from the Inside") and the C5 ("All Corvettes are Red") and the inner workings of GM.

I had a Chevy Vega which was a full unibody frame. That was just fine until I but a high HP V8 with an automatic transmission.
In a matter of months, the doors, hood and trunk gaps were all tweeked.
