I'm pretty sure that it was the Starliner top that won NASCAR for them! I was just reading a piece about how Ford's top profile change in '62 took them out of the running, to the end that they tried a trick move to qualify another profile - https://macsmotorcitygarage.com/ford...KhO4dr9EvUME_w

The Crown Vic's became the vehicle of choice for law enforcement for many years, and they were great cruisers. Seems to me that your swap should be a good one! Looking forward to seeing your progress, if you plan to start a build log.... And a Ranch Wagon!! Super Cool!
