Re: '57 42 foot Constellation. Trying to reduce 14' 6" height for road transport
We bought our Chris Craft in East Tawas, Michigan ... had it trucked to St. Charles (St. Louis), Missouri. The windshield had to be removed for transport. Yours will be a lot more work due to hard top, but it can certainly be done ... you WILL have to rewire/reconnect anything going to the glass (think wipers) and anything running up/in/through the hardtop. We did it 25 years ago ...
LOVE that model, BTW!!! Good luck.
Nothing else matters but how I raise my children ... and their opinion of me, as a father.
