There is an original 55 convertible for sale on facebook that you might be interested in. The picture he took before he started restoring it looked like it was an exceptionally clean California car. It is now all apart but painted. The price may seem high, but you have to add up what a car will cost with all the additions you plan for your car.
If you go for the after market body minus front clip (19K?), you will need a conv parts car which could be (10-15K). Body and Paint work depends on the quality you want, and the upgrades you want will also add up quickly.
This is his listing on facebook, which includes a 20K Morrison chassis, and many other desirable parts.
