Depends on how thorough the conversion was. Sometimes all that was done was add a LP tank and regulator, then drill and tap the air horn of the carburetor for a pipe fitting to connect the LP line from the regulator. If the LP tank is on the front, likely the original gas tank is still there. If all this holds true and all the stock parts are intact, then switching back to gas would be easy.
