My thought was that since they are from the same, AMT, company and supposed to be the same scale they would fit. I'm sure there would be some adjustments. I did a roof swap between the hardtop from the old '57 Ford AMT kit and the much newer Revell '57 Ford two door sedan to make a low line '57 Ford hardtop. While the width wasn't thew problem so much as the hardtop having a flatter crown in the roof than the sedan, but it worked out.
