55.2-59 The Door seals don’t

[Roarinrat]

Hi
I have got the door shut lines on my 56 GMC perfect, and installed new door seals. The problem is that they don’t fit at all well, to the extent that I can see daylight through the leading edge of the door when I’m in the drivers seat.
At 60 mph it’s like a windy day in the cab.
The seals are made by Counter Part.
Has anyone had a similar experience with Counter Part seals, or is there an alternative maker that has a larger cross section seal?
Looking forward to hearing you thoughts.
Steve
