No discussion on my doors, just showing you that 51s fit on a 54! The red doors were 51s and now it has 54s.
I would suggest cutting all the way around the roof near the leading, side, and trailing edges and replacing it that way. You will leave the structural integrity of the 4 corners without trying to figure out what you need to do on the windshield, it will stay a '53. If you want to swap, you'll need the lower edge of the '54 opening to replace yours and it will be more welding fun. I'd scalp it and swap that way.
I'd wait until I could find a split windshield top. I'd also go for a 5 window cab and chop it! Then I'd send the '54 windshield to me and I'd put it in my truck. But that's just me.
