LEAVE IT ALONE!!! You can't swing a dead cat by tail anymore without hitting a "Deluxe" Roadster! They're as common as illegal aliens these days. Everyone seems to feel the need to take innocent Standard Roadsters and convert them to DeLuxes. It's getting harder and harder to find unmolested Standard Roadsters, especially with trunks instead of rumble seats.
You'll get the usual advice that it's your car - do what you want with it. But if you do make the conversion, you will have lost a piece of automotive Americana that will be difficult to recover. Consider yourself very fortunate to have acquired a true Standard Roadster. Not many guys have such an animal in captivity. My first sentence bears repeating: LEAVE IT ALONE!!!
