1955-1957 wagon roof?

[57sailplane]

so i just bought a 1957 handyman wagon. the roof skin is so bad that a whole skin will have to be replaced. i have watched videos on replacing the roof from the pillars up but this seems like a lot more work then needed. also to find a 2door wagon roof is a lot harder to find.

my question is since i have read that the 57 windshields are different at the cowl then the 55 and 56's. Are the roofs different between these years? also is there any difference from a 2 to 4 door? or are the roof the same like the hardtops and the sedans. like what i see for new roof skin replacement on the hardtops and sedans 55-57 they fit all?

thanks in advance Andrew K.

also am i thinking about it wrong by cutting the old roof skin off, fix the inner structure then spot the knew skin on or do i need to go about as if i were doing a chop and cut pillers as i have seen someone else do it. seem like more engineering and measuring doing it like a chop.

thanks again. later.
