Hi, I'm building a 1933 phaeton with parts from here and there and right now i'm doing the top and for some reason i can't explain, the header is two and a half inches forward of the windshield posts. I've been thinking if maybe australian phaetons seem to be a little bet longer than the ones made in America because they have a wider door pillar and maybe their top irons are longer too or maybe the their windshield posts are a little bet more slanted to compensate and i'm using australian windshield posts in an american body. If some body have any experience on this, i'll appresiate any help. thank you
