Projects Winshield frame help please

Is the bottom radius or curve on a 26-27 model T closed car the same as a 29 model A 5 window radius (windshield frame)?

Thanks in advance!

 

I don't think it is the same .My 27 t coupe is wider at the top than the bottom.I couldn't find a original one around Denver so I made mine from Strap steel with a piano hinge at the top.Then I made a channel to set the glass in the frame.It appears stock. Speedway out of Lincoln Nebraska sells a alluninum one that looks nice but is a little flimsy and pricy($209.00 plane alum and $319.00 pollished) so I made one costing about $20. for materials.
