'56 Cab Wind Noise

[ford37502]

Picked up a really sweet '56 pickup a couple of months ago for an incredible price. It was built with all the right stuff, but I have an incredible issue with wind noise around the doors. The cab has all new weatherstripping installed and the latches seem to be set right ... the back of the doors are flush to the cab openings. I took a dollar bill and closed it in the door in several places and it slid out with zero resistance, so the seals aren't touching. Have no idea the manufacturer of the seals but they appear to be good quality. Any thoughts for next steps to take?? I REALLY do not want to drive a vehicle with that kond of noise. Thanks for any suggestions
