yes, if you have 4x4 metal that will fit.
and no, the roof curves at the corners. I have a 35x20 and it has to be notched to curve with the roof, I couldnt imagine much wider fitting well or looking good or both, but hey, nothing says you cant just take out a tape measure and mark out the roof to see if I am wrong. I have been before, I will be again.
