I got these kits about 6 months ago to build this.While waiting for decent painting weather and the arrival of parts for my 56 Impala I got them out..
My first thought were to cut through the roof and reassemble things but then the better got to me so I kept the top in tact,,,,Slicing the coupe on the door line and the 2 door to match so when put back. . The sedan got the post cut out to move back for the back door/rear window. The coupe pillar that was left was cut and reunited with the front door. I should have cut them out together in 1 piece..harder to cut but easier to put back. Some finish work and new hole for the rear door handle and then assemble per directions using the 2 door sedan for interior.
